As images of the bodies — of people whom residents said were killed indiscriminately — began to emerge from Bucha, a slew of European leaders condemned the atrocities and called for tougher sanctions against Moscow.

So far, the bodies of 410 civilians have been found in Kyiv-area towns that were recently retaken from Russian forces, Ukraine's prosecutor-general, Iryna Venediktova, said.

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, another's legs were bound.

Ukrainian officials laid the blame for the killings in Bucha and other Kyiv suburbs 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 around the capital, territory that has seen heavy fighting since troops invaded Ukraine from three directions on Feb. 24. Troops who swept in from Belarus to the north spent weeks trying to clear a path to Kyiv, but their advance stalled in the face of resolute defense from Ukraine's forces.

Moscow now says it is focusing its offensive on the country's east, but it also pressed a siege on a city in the north and continued to strike cities elsewhere in a war that has left thousands dead and forced more than 4 million Ukrainians to flee their country.

Russian troops rolled into Bucha in the early days of the invasion and stayed up to March 30. With those forces gone, residents gave harrowing accounts Sunday, saying soldiers shot and killed civilians without any apparent reason.

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 and taking them away or shooting them.

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

“He went to get some wood when all of a sudden they (Russians) started shooting. 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 chest). And another shot went slightly below the temple. It was a controlled shot to the head.”

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.

The resident who refused to be identified said the man was killed as he left a home.

“He put his hands up, and they shot him,” he said.

Oleksiy Arestovych, an adviser to Ukrainian President Volodymyr Zelenskyy, described bodies lying the streets of the suburbs of Irpin and Hostomel as well as Bucha as a “scene from a horror movie.” He alleged that some of the women found dead had been raped before being killed and the Russians then burned the bodies.

“This is genocide,” Zelenskyy told CBS' “Face the Nation” on Sunday.

In a post later Sunday on Telegram, he asked Russian mothers to watch what is happening, saying they have raised “murderers, marauders, executioners.”

But Russia's Defense Ministry said in a statement that the photos and videos of dead bodies “have been stage managed by the Kyiv regime for the Western media.” It noted that Bucha's mayor did not mention any abuses a day after Russian troops left.

The ministry charged said “not a single civilian has faced any violent action by the Russian military" in Bucha.

In Motyzhyn, some 50 kilometers (30 miles) west of Kyiv, residents told AP on Sunday 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.
