BUCHA, Ukraine (AP) — Bodies with bound hands, close-range gunshot wounds and signs of torture lay scattered in a city on the outskirts of Kyiv after Russian soldiers withdrew from the area. Ukrainian authorities accused the departing forces on Sunday of committing war crimes and leaving behind a “scene from a horror movie.”

As images of the bodies emerged from Bucha, European leaders condemned the atrocities and called for tougher sanctions against Moscow. In a sign of how the horrific reports shook many leaders, Germany’s defense minister even suggested that the European Union consider banning Russian gas imports.

Ukrainian officials said the bodies of 410 civilians were found in Kyiv-area towns that were recently retaken from Russian forces.

Associated Press journalists saw the bodies of at least 21 people in various spots around Bucha, northwest of the capital. One group of nine, all in civilian clothes, were scattered around a site that residents said Russian troops used as a base. They appeared to have been killed at close range. At least two had their hands tied behind their backs, one was shot in the head, and another’s legs were bound.

Ukrainian officials laid the blame for the killings squarely at the feet of Russian troops, with the president calling them evidence of genocide. But Russia’s Defense Ministry rejected the accusations as “provocation.”

The discoveries followed the Russian retreat from the area after Moscow said it was focusing its offensive on the country’s east. Russian troops had rolled into Bucha in the early days of the invasion and stayed up until March 30.

One resident, who refused to give his name out of fear for his safety, said that Russian troops went building to building and took people out of the basements where they were hiding, checking their phones for any evidence of anti-Russian activity before taking them away or shooting them.

Hanna Herega, another resident, said Russian troops started shooting at a neighbor who had gone out to gather wood for heating.

“They hit him a bit above the heel, crushing the bone, and he fell down,” Herega said. “Then they shot off his left leg completely, with the boot. Then they shot him all over.”

The AP also saw two bodies, that of a man and a woman, wrapped in plastic that residents said they had covered and placed in a shaft until a proper funeral could be arranged.

“He put his hands up, and they shot him,” said the resident who refused to be identified.

Oleksiy Arestovych, an adviser to Ukrainian President Volodymyr Zelenskyy, described bodies lying in suburban streets as a “scene from a horror movie.” He claimed some of the women had been raped before being killed and the Russians then burned the bodies.

In a video address, Zelenskyy said Russian soldiers who killed and tortured civilians were responsible for “concentrated evil.”

“It is time to do everything possible to make the war crimes of the Russian military the last manifestation of such evil on earth,” he said in remarks translated by his office.

He directed some of his remarks at the mothers of Russian soldiers involved.

“Even if you raised looters, how did they also become butchers?” he said. “You couldn’t overlook that they are deprived of everything human. No soul. No heart. They killed deliberately and with pleasure.”

Zelenskyy said his government would take steps to create a special justice mechanism to investigate every crime committed by the Russian forces in Ukraine.

Zelenskyy also appeared in a pre-recorded video message at Sunday’s Grammy Awards, contrasting the lives of those attending the award ceremony in Las Vegas with the lives of musicians in his battered homeland.

“Our musicians wear body armor instead of tuxedos. They sing to the wounded in hospitals, even to those who can’t hear them,” he said in English. “But the music will break through anyway.”

Russia’s Defense Ministry said in a statement that photos and videos of dead bodies “have been stage managed by the Kyiv regime for the Western media.”

The ministry said “not a single civilian” in Bucha had faced any violent military action and the mayor did not mention any abuses a day after Russian troops left.

Russia asked for a meeting Monday of the U.N. Security Council to discuss events in the city. The U.S. and Britain have recently accused Russia of using Security Council meetings to spread disinformation.

In Motyzhyn, some 50 kilometers (30 miles) west of Kyiv, residents told AP that Russian troops killed the town’s mayor, her husband and her son and threw their bodies into a pit in a pine forest behind houses where Russian forces had slept.

Inside the pit, AP journalists saw four bodies of people who appeared to have been shot at close range. The mayor’s husband had his hands behind his back, with a piece of rope nearby, and a piece of plastic wrapped around his eyes like a blindfold.

Ukrainian Deputy Prime Minister Iryna Vereshchuk confirmed that the mayor was killed while being held by Russian forces.

Some European leaders said the killings in the Kyiv area amounted to war crimes. The U.S. has previously said that it believes Russia has committed war crimes, and Secretary of State Anthony Blinken called images of what happened near Kyiv “a punch to the gut” on CNN’s “State of the Union.”

“It is a brutality against civilians we haven’t seen in Europe for decades,” NATO Secretary-General Jens Stoltenberg said on the same show.

Kyiv Mayor Vitali Klitschko called on nations to immediately end Russian gas imports, saying they were funding the killings.

In a turnaround, Germany’s defense minister said that the EU should consider doing just that. Ministers “would have to talk about halting gas supplies from Russia,” Defense Minister Christine Lambrecht said on German public broadcaster ARD. “Such crimes must not go unanswered.”

Russia provides 40% of Europe’s gas and 25% of its oil, and until now many EU nations have resisted calls to scale back or fully end reliance on Russian fossil fuels. Giving them up would mean even higher prices at the pump and higher utility bills, potentially creating an energy crisis and a recession.

The U.S. has previously announced a ban on Russian oil, but it imports only a small share of Russia’s oil exports and doesn’t buy any of its natural gas.

As Russian forces retreated from the area around the capital, they also withdrew from the Sumy region, in Ukraine’s northeast, local administrator Dmitry Zhivitsky said in a video message carried by Ukrainian news agencies. The troops had occupied the area for nearly a month.

They pressed their sieges in other parts of the country. Russia has said it is directing troops to the Donbas in eastern Ukraine, where Russia-backed separatists have been fighting Ukrainian forces for eight years.

In that region, Mariupol, a port on the Sea of Azov that has seen some of the war’s greatest suffering, remained cut off. About 100,000 civilians — less than a quarter of the prewar population of 430,000 — are believed to be trapped there with little or no food, water, fuel and medicine.

The International Committee of the Red Cross said Sunday that a team sent Saturday to help evacuate residents had yet to reach the city.

Ukrainian authorities said Russia agreed days ago to allow safe passage from the city, but similar agreements have broken down repeatedly under continued shelling.

The mayor of Chernihiv, which has also been cut off from shipments of food and other supplies for weeks, said that relentless Russian shelling has destroyed 70% of the northern city.

The Ukrainian military said early Monday that its forces had retaken some towns in the Chernihiv region and that humanitarian aid was being delivered. The road between Chernihiv and the capital, Kyiv, was to reopen to some traffic later in the morning, according to the news agency RBK Ukraina.

The regional governor in Kharkiv said that Russian artillery and tanks launched over 20 strikes on Ukraine’s second-largest city and its outskirts in the country’s northeast over the past day.

The head of Ukraine’s delegation in talks with Russia said Moscow’s negotiators informally agreed to most of a draft proposal discussed during face-to-face talks in Istanbul this week, but no written confirmation has been provided.

The Russian invasion has left left thousands dead and forced more than 4 million Ukrainians to flee their country.

KYIV, Ukraine (AP) — Russian troops left the heavily contaminated Chernobyl nuclear site early Friday after returning control to the Ukrainians, authorities said, as eastern parts of the country braced for renewed attacks and Russians blocked another aid mission to the besieged port city of Mariupol.

Ukraine’s state power company, Energoatom, said the pullout at Chernobyl came after soldiers received “significant doses” of radiation from digging trenches in the forest in the exclusion zone around the closed plant. But there was no independent confirmation of that.

The exchange of control happened amid growing indications the Kremlin is using talk of de-escalation in Ukraine as cover to regroup, resupply its forces and redeploy them for a stepped-up offensive in the eastern part of the country.

Ukrainian President Volodymyr Zelenskyy warned that Russian withdrawals from the north and center of the country were just a military tactic to build up forces for new powerful attacks in the southeast. A new round of talks between the countries was scheduled Friday, five weeks into a conflict that has left thousands dead and driven 4 million Ukrainians from the country.

“We know their intentions,” Zelenskyy said in his nightly video address to the nation. “We know that they are moving away from those areas where we hit them in order to focus on other, very important ones where it may be difficult for us.”

“There will be battles ahead,” he added.

Meanwhile in Mariupol, Russian forces blocked a convoy of 45 buses attempting to evacuate people after the Russian military agreed to a limited cease-fire in the area. Only 631 people were able to get out of the city in private cars, according to the Ukrainian government.

Russian forces also seized 14 tons of food and medical supplies in a dozen buses that were trying to make it to Mariupol, Deputy Prime Minister Iryna Vereshchuk said.

The city has been the scene of some of the worst suffering of the war. Tens of thousands have managed to get out in the past few weeks by way of humanitarian corridors, reducing the population from a prewar 430,000 to an estimated 100,000 by last week, but other relief efforts have been thwarted by continued Russian attacks.

The International Atomic Energy Agency said it had been informed by Ukraine that the Russian forces at the site of the world’s worst nuclear disaster had transferred control of it in writing to the Ukrainians. The last Russian troops left early Friday, the Ukrainian government agency responsible for the exclusion zone said.

Energoatom gave no details on the condition of the soldiers it said were exposed to radiation and did not say how many were affected. There was no immediate comment from the Kremlin, and the IAEA said it had not been able to confirm the reports of Russian troops receiving high doses. It said it was seeking more information.

Russian forces seized the Chernobyl site in the opening stages of the Feb. 24 invasion, raising fears that they would cause damage or disruption that could spread radiation. The workforce at the site oversees the safe storage of spent fuel rods and the concrete-entombed ruins of the reactor that exploded in 1986.

Edwin Lyman, a nuclear expert with the U.S.-based Union of Concerned Scientists, said it “seems unlikely” a large number of troops would develop severe radiation illness, but it was impossible to know for sure without more details.

He said contaminated material was probably buried or covered with new topsoil during the cleanup of Chernobyl, and some soldiers may have been exposed to a “hot spot” of radiation while digging. Others may have assumed they were at risk too, he said.

Early this week, the Russians said they would significantly scale back military operations in areas around Kyiv and the northern city of Chernihiv to increase trust between the two sides and help negotiations along.

But in the Kyiv suburbs, regional governor Oleksandr Palviuk said on social media Thursday that Russian forces shelled Irpin and Makariv and that there were battles around Hostomel. Ukrainian forces counterattacked and some Russian withdrawals around the suburb of Brovary to the east, Pavliuk said.

At a Ukrainian military checkpoint outside Kyiv, soldiers and officers said they don’t believe Russian forces have given up on the capital.

“What does it mean, significantly scaling down combat actions in the Kyiv and Chernihiv areas?” asked Brig. Gen. Valeriy Embakov. “Does it mean there will be 100 missiles instead of 200 missiles launched on Kyiv or something else?”

Chernihiv came under attack as well. At least one person was killed and four were wounded in the Russian shelling of a humanitarian convoy of buses sent to Chernihiv to evacuate residents cut off from food, water and other supplies, said Ukrainian Human Rights Commissioner Lyudmyla Denisova.

Elsewhere, Ukraine reported Russian artillery barrages in and around the northeastern city of Kharkiv.

Ukraine’s emergency services also said the death toll had risen to 20 in a Russian missile strike Tuesday on a government administration building in the southern city of Mykolaiv.

NATO Secretary-General Jens Stoltenberg said intelligence indicates Russia is not scaling back its military operations in Ukraine but is instead trying to regroup, resupply its forces and reinforce its offensive in the Donbas.

“Russia has repeatedly lied about its intentions,” Stoltenberg said. At the same time, he said, pressure is being kept up on Kyiv and other cities, and “we can expect additional offensive actions bringing even more suffering.”

The Donbas is the predominantly Russian-speaking industrial region where Moscow-backed separatists have been battling Ukrainian forces since 2014. In the past few days, the Kremlin, in a seeming shift in its war aims, said that its “main goal” now is gaining control of the Donbas, which consists of the Donetsk and Luhansk regions, including Mariupol.

The top rebel leader in Donetsk, Denis Pushilin, issued an order to set up a rival city government for Mariupol, according to Russian state news agencies, in a sign of Russian intent to hold and administer the city.

With talks set to resume between Ukraine and Russia via video, there seemed little faith that the two sides would resolve the conflict any time soon.

Russian President Vladimir Putin said that conditions weren’t yet “ripe” for a cease-fire and that he wasn’t ready for a meeting with Zelenskyy until negotiators do more work, Italian Premier Mario Draghi said after a telephone conversation with the Russian leader.

As Western officials search for clues about what Russia’s next move might be, a top British intelligence official said demoralized Russian soldiers in Ukraine are refusing to carry out orders and sabotaging their equipment and had accidentally shot down their own aircraft.

U.S. intelligence officials have concluded that Putin is being misinformed by his advisers about how badly the war is going because they are afraid to tell him the truth.

Kremlin spokesman Dmitry Peskov said that the U.S. is wrong and that “neither the State Department nor the Pentagon possesses the real information about what is happening in the Kremlin.”

KYIV, Ukraine (AP) — The Ukrainian president said his country’s defense against the Russian invasion is at a “turning point” and again pressed the United States for more help, hours after the Kremlin’s forces reneged on a pledge to scale back some of their operations.

Russian bombardment of areas around Kyiv and the northern city of Chernihiv and intensified attacks elsewhere in the country further undermined hopes for progress toward ending the brutal war. Talks between Ukraine and Russia were set to resume Friday by video, according to the head of the Ukrainian delegation, David Arakhamia.

A delegation of Ukrainian lawmakers visited Washington on Wednesday to push for more U.S. assistance, saying their nation needs more military equipment, more financial help and tougher sanctions against Russia.

“We need to kick Russian soldiers off our land, and for that we need all, all possible weapons,” Ukrainian parliament member Anastasia Radina said at a news conference at the Ukrainian Embassy.

Ukrainian President Volodymyr Zelenskyy made the case directly to U.S. President Joe Biden.

“If we really are fighting for freedom and in defense of democracy together, then we have a right to demand help in this difficult turning point. Tanks, aircraft, artillery systems. Freedom should be armed no worse than tyranny,” Zelenskyy said in his nightly video address to the nation, which he delivered standing in the dark outside the dimly lit presidential offices in Kyiv. He thanked the U.S. for an additional $500 million in aid that was announced Wednesday.

There seemed little faith that Russia and Ukraine will resolve the conflict soon, particularly after the Russian military’s about-face and its most recent attacks.

Russia said Tuesday that it would de-escalate operations near Kyiv and Chernihiv to “increase mutual trust and create conditions for further negotiations.” Zelenskyy and the West were skeptical. Soon after, Ukrainian officials reported that Russian shelling was hitting homes, stores, libraries and other civilian sites in or near those areas.

Russian troops also stepped up their attacks on the Donbas region in the east and around the city of Izyum, which lies on a key route to the Donbas, after redeploying units from other areas, the Ukrainian side said.

Olexander Lomako, secretary of the Chernihiv city council, said the Russian announcement turned out to be “a complete lie.”

“At night they didn’t decrease, but vice versa increased the intensity of military action,” Lomako said.

A top British intelligence official said Thursday that demoralized Russian soldiers in Ukraine were refusing to carry out orders and sabotaging their own equipment and had accidentally shot down their own aircraft.

In a speech in the Australian capital Canberra, Jeremy Fleming, who heads the GCHQ electronic spy agency, said President Vladimir Putin had apparently “massively misjudged” the invasion, he said. Although Putin’s advisers appeared to be too afraid to tell the truth, the “extent of these misjudgments must be crystal clear to the regime,” he said.

U.S. intelligence officials have given similar assessments that Putin is being misinformed by his advisers about the poor performance of his military in Ukraine because they are too afraid to tell him the truth.

Five weeks into the invasion that has left thousands dead on both sides, the number of Ukrainians fleeing the country topped a staggering 4 million, half of them children, according to the United Nations.

“I do not know if we can still believe the Russians,” Nikolay Nazarov, a refugee from Ukraine, said as he pushed his father’s wheelchair at a border crossing into Poland. “I think more escalation will occur in eastern Ukraine. That is why we cannot go back to Kharkiv.”

Zelenskyy said the continuing negotiations with Russia were only “words without specifics.” He said Ukraine was preparing for concentrated new strikes on the Donbas.

Zelenskyy also said he had recalled Ukraine’s ambassadors to Georgia and Morocco, suggesting they had not done enough to persuade those countries to support Ukraine and punish Russia for the invasion.

“With all due respect, if there won’t be weapons, won’t be sanctions, won’t be restrictions for Russian business, then please look for other work,” he said.

During talks Tuesday in Istanbul, the faint outlines of a possible peace agreement seemed to emerge when the Ukrainian delegation offered a framework under which the country would declare itself neutral — dropping its bid to join NATO, as Moscow has long demanded — in return for security guarantees from a group of other nations.

Top Russian officials responded positively, with Foreign Minister Sergey Lavrov saying Wednesday that Ukraine’s willingness to accept neutrality and look outside NATO for security represents “significant progress,” according to Russian news agencies.

But those statements were followed by attacks.

Oleksandr Pavliuk, head of the Kyiv region military administration, said Russian shells targeted residential areas and civilian infrastructure in the Bucha, Brovary and Vyshhorod regions around the capital.

Russian Defense Ministry spokesman Maj. Gen. Igor Konashenkov said the military also targeted fuel depots in two towns in central Ukraine with air-launched long-range cruise missiles. Russian forces hit a Ukrainian special forces headquarters in the southern Mykolaiv region, he said, and two ammunition depots in the Donetsk region, in the Donbas.

In southern Ukraine, a Russian missile destroyed a fuel depot in Dnipro, the country’s fourth-largest city, regional officials said.

The U.S. said Russia had begun to reposition less than 20% of its troops that had been arrayed around Kyiv. Pentagon press secretary John Kirby said troops from there and some other zones began moving mostly to the north, and some went into neighboring Belarus. Kirby said it appeared Russia planned to resupply them and send them back into Ukraine, but it is not clear where.

The Ukrainian military said some Russian airborne units were believed to have withdrawn into Belarus.

In northern Ukraine, Russian forces took no offensive actions Wednesday, focusing on reconnaissance and logistics, the general staff said in a statement. But Russia is expected to increase attacks soon to protect its own troops as they are repositioned, it said.

The Russians also are expected to try to blockade Chernihiv.

Top Russian military officials say their main goal now is the “liberation” of the Donbas, the predominantly Russian-speaking industrial heartland where Moscow-backed separatists have been battling Ukrainian forces since 2014.

Some analysts have suggested that the focus on the Donbas and the pledge to de-escalate may merely be an effort to put a positive spin on reality: Moscow’s ground forces have been thwarted — and have taken heavy losses — in their bid to seize the capital and other cities.

In other developments:

— The U.N. is looking into allegations some residents of the besieged and shattered southern city of Mariupol were forcibly taken to areas controlled by Russian forces or to Russia itself.

— Germany said Russia had reassured it European companies won’t have to pay for Russian gas in rubles, a prospect that raised fears Russia could cut off supplies. Also, Poland said it would end Russian oil imports by the year’s end.
