Ukraine reportedly launched at least 337 drones into Russia on Tuesday in the largest-yet drone attack of the Moscow-Kyiv conflict, according to the Russian Ministry of Defense. It came just before US and Ukrainian delegations were scheduled to meet for negotiation discussions in Jeddah, Saudi Arabia on Tuesday. Russia set the previous drone-attack record a little over two weeks ago, when it launched 267 drones at Ukraine in a single night on Feb. 23.
