KYIV, Aug 17 – The McFaul-Yermak Group will soon publish additional proposals to strengthen sanctions against companies and individuals that, bypassing sanctions, supply Russia with high-tech components for production of weapons, in particular K-52 helicopters, head of the President's Office of Ukraine Andriy Yermak said.

"The two Russian Ka-52 helicopters shot down today could not fly without foreign components. The military constantly says that the Russians are actively using them at the front to have an advantage in the air and strike at the positions of the Defense Forces. Our specialists have been studying the Ka-52 for a long time," Yermak wrote on the Telegram channel on Thursday.
