The United States is accusing Russia of a “dangerous and inexplicable escalation” of the nearly four-year war in Ukraine at a time when the Trump administration is trying to advance negotiations toward peace.

Russia attacked Ukraine overnight with 242 drones and 36 missiles, the Ukrainian Air Force said Friday morning.

Russia says it used its new Oreshnik hypersonic missile and other weapons in a massive strike on Ukraine​. Ukrainian President Zelenskyy says a drone hit the Qatar embassy.

Ukrainian authorities reported multiple deaths and infrastructure damage after Russia said it deployed a new missile system in an overnight strike.

The hypersonic Oreshnik intermediate range ballistic missile hit Ukraine's western Lviv region late Thursday night, although officials there did not mention any casualties.

Ukraine's commander in chief said December was the first month that its drones "neutralized" roughly as many Russians as were called up.

The Ukrainian Air Force said on Tuesday that Russian forces had launched 293 drones and 18 missiles in the bombardment that began late on Monday, as the country faces its harshest winter since the start of Moscow’s full-scale invasion in 2022.

It came after Russia launched its heaviest air attack of 2026, killing four in strikes targeting Kyiv and Kharkiv
