In a rare admission, Russia claims that Ukraine used US-supplied Atacms missiles to strike an air base and a vital air defense system in the Kursk region.
A day after Ukraine claimed to have struck targets in the area, the defense ministry issued a statement threatening reprisal.
Meanwhile, Ukraine’s air force reported that Russia damaged vital infrastructure on Monday night by launching a record 188 drones in a single attack.
Since the US allegedly permitted Ukraine to launch Atacms missiles against targets within Russia last week in retaliation for Russia’s deployment of North Korean troops, tensions have been high.
Russia’s use of the potent new intermediate-range Oreshnik ballistic missile against the Ukrainian city of Dnipro marked the end of the week.
