KYIV, Ukraine 

The Ukrainian prosecutor general's office said Monday that the bodies of five people tortured by the Russian army were found in the city Bucha near the capital Kyiv.

They were discovered in the basement of a children's health center with their hands tied, the office said in a statement.

"Soldiers of the Russian Armed Forces tortured and then killed unarmed civilians," it said, adding police and prosecutors continue to record each war crime at the scene.

The bodies of at least 410 civilians were recovered in Bucha on Sunday, according to the prosecutor general.

Russia has denied that its troops killed civilians while withdrawing from towns near Kyiv.

Russia’s war against Ukraine, which started on Feb. 24, has been met with international outrage, with the European Union, US and UK, among others, implementing tough sanctions on Moscow.

At least 1,430 civilians have been killed in Ukraine and 2,097 injured, according to UN estimates, with the true figure feared to be far higher.

More than 4.21 million Ukrainians have also fled to other countries, with millions more internally displaced, according to the UN refugee agency.
