Ukraine pummeled two Russian regions with drones on Tuesday as its ground forces tried to smash through defensive lines in a bid to carve out even more territory during its biggest attack on Russia's side of the border since the war began.
Ukrainian soldiers crossed the Russian border, about 530 km (330 miles) southwest of Moscow, a week ago, in a surprise attack that President Vladimir Putin said was aimed at both improving Kyiv's negotiating position ahead of possible talks and slowing the advance of Russian forces along the rest of the front.
Russia's defense ministry said its air defense units destroyed 12 drones over the Kursk region, one over the Belgorod region and one over Voronezh. Russian officials in Kursk and Belgorod put out warnings of missile attacks.
