WASHINGTON — The United States is selling weapons to its NATO allies in Europe so they can provide them to Ukraine as it struggles to fend off a recent escalation in Russia’s drone and missile attacks, President Donald Trump and his chief diplomat said.

Russia launched its largest drone and missile bombardment of Ukraine overnight into Wednesday, according to Ukrainian President Volodymyr Zelenskyy.

Ukrainian officials say that Russia pounded the capital with yet another mass missile and drone attack, causing fires across the city and injuring at least 10 people a day after the heaviest aerial attack of the war so far.

KYIV, Ukraine — Russia fired more than 100 drones at civilian areas of Ukraine overnight, authorities said Monday, as the Kremlin dismissed the country’s transport chief after a weekend of travel chaos when Russian airports grounded hundreds of flights due to the threat of Ukrainian drone attacks.
