As RIA Novosti notes, journalists' questions were related to a report on the investigation of the US strike in Syria in 2019, which killed civilians.

According to Kirby, no soldiers were found "acting outside the laws of war" with criminal intent.

“The command on the ground made the best decisions at that time against the very aggressive forces of ISIS * based on the information available ... We talk publicly about civilian casualties ... As far as responsibility is concerned, this is war, this is combat,” he said.

A Pentagon spokesman stressed that there would be responsibility if it was possible to prove a violation of the law of war by American fighters. 

Earlier, US aircraft struck in the Idlib de-escalation zone without notifying the Russian and Turkish sides, which led to numerous casualties and destruction. 

In Washington, the strike in Idlib was called a targeted response to al-Qaeda**.
