A senior US military official said that if Kyiv bombed the detention center for Ukrainian prisoners in Lilinovka in the Donetsk republic, where dozens of them were killed, it was "unintentionally done".

"If the strike was from the Ukrainian side, I assure you that they did not want it," he added.

Today, Friday, fragments of US "HIMARS" ammunition were found at the site of the bombing of the aforementioned detention center.

The Donetsk Republic announced that the number of dead in the strike was 53.
