Russia's Defense Ministry admitted Ukraine targeted its Kursk region with U.S.-supplied Atacms missiles, striking an air-defense battalion and an air base, according to the BBC. Russia's Defense Ministry reported that two of five Atacms missiles struck their target, damaging a radar system and causing casualties. Ukraine's air force also reported Russia launched a record 188 drones overnight, causing significant damage to infrastructure. Moscow promised retaliation, as tensions rose following U.S. approval for Ukraine to use Atacms missiles inside Russia. BBC Verify confirmed the footage from Kursk city as genuine but could not confirm if U.S.-supplied missiles caused the flashes.
