US weapons are forcing Russians to step back in Ukraine: Kyiv deputy

Ukrainian forces have been able to stop Russia's summer Kharkiv offensive with the help of American weapons, according to a senior Ukrainian lawmaker, with U.S. arms used to target especially valuable systems including advanced air defense platforms.

"We stopped the Russian offensive operation," Yehor Cherniev, a member of the Ukrainian Parliament and the deputy head of its national security, defense and intelligence committee, told Newsweek on Thursday.
