KYIV, Ukraine (AP) — Russia launched a second major drone and missile bombardment of Ukraine in four days, officials said Tuesday, aiming again at the power grid and apparently snubbing U.S.-led peace efforts as the war approaches the four-year mark.

Russia fired almost 300 drones, 18 ballistic missiles and seven cruise missiles at eight regions overnight, Ukrainian President Volodymyr Zelensky said on social media.

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.

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.

On Monday, the United States accused Russia of a " dangerous and inexplicable escalation " of the fighting, when the Trump administration is trying to advance peace negotiations.

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