At least 20 bodies littered the streets of the Kyiv suburb of Bucha after the town was reclaimed from Russian forces, AFP reported.

According to the report, all of the bodies wore civilian clothing.

Three people were killed while riding bicycles, others were killed in or next to their cars. At least one person had his hands tied behind his back when he was killed.

Bucha Mayor Anatoly Fedoruk told AFP that all the victims were killed execution style by shots to the back of the head.

A further 380 bodies were found in mass graves.

Advisor to the Minister of Internal Affairs of Ukraine Anton Gerashchenko said that "It was a very difficult evening today. More and more bodies of civilians killed by the invaders are found in the liberated suburbs of Kyiv. These fascist animals took their lives. It is impossible to believe that this is happening in the twenty-first century."

Ukraine said on Saturday that its forces had seized back all areas around the capital Kyiv, claiming complete control of the capital region for the first time since Russia launched the invasion, Reuters reported.

Ukraine's troops have retaken more than 30 towns and villages around Kyiv since Russia pulled back from the area this week, Ukrainian officials said.

"The whole Kyiv region is liberated from the invader," Ukraine's Deputy Defense Minister, Hanna Malyar, wrote on Facebook. There was no Russian comment on the claim, which Reuters could not immediately verify.
