"Enemy troops are massing now, they are regrouping. We're getting ready to repel a new attack," a deputy commanding officer of a brigade of the Armed Forces of Ukraine told TSN.

Journalists are not allowed to visit the front line, but the military insist it was a counter attack last night.

"I completely refute reports that our troops were first to strike. It was the enemy who first opened preparation fire, then launched an offensive," head of the press center of the Anti-Terrorist Operation (ATO) headquarters Hryhoriy Mazur said.
