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 Riyadh on Tuesday.

The Ukrainian military said on Wednesday that Russia launched three missiles and 133 drones in an overnight attack. It said the air force shot down 98 drones. Another 20 drones did not reach their targets,

The assault, which the mayor called the largest on Russia’s capital since the war began, was a reminder of Ukraine’s power to strike as its president proposes an air truce.

Russian air defenses shot down over 300 Ukrainian drones over 10 Russian regions overnight, military officials said Tuesday, in what appeared to be the biggest Ukrainian drone attack on Russia in the three-year war.

Russia said it had downed more than 300 Ukrainian drones just hours before the first high-level talks between Washington and Kyiv since a tense Oval Office meeting.
