“We have only recently seen fresh data on this,” Kirby said, quoted by TASS.

He added that, "presumably, a barrack with Ukrainian prisoners of war was hit."

“But we cannot confirm this, so I think I need to refrain,” the official added.

At the same time, as RIA Novosti reported, a senior Pentagon official said that "if it was a strike from the Ukrainian side," then "they didn't want to do it."

According to the Russian Ministry of Defense, the Armed Forces of Ukraine fired at the detention center in Yelenovka with the captured Ukrainian military and militants located there using the American HIMARS multiple launch rocket system.

According to the latest data, the death toll from the impact has risen to 53.

The Investigative Committee of Russia opened a criminal case after the strike of the Armed Forces of Ukraine.
