Russia launched nearly 100 attacks in the Kursk region in the last 24 hours, according to the latest update from the Ukrainian general staff, in a bid to reverse Kyiv’s recent gains. It made up nearly half of the assaults reported by Ukraine over the last day across the entire, roughly 640-mile front line.

Ukraine said on Tuesday its forces were "commencing new offensive actions" in Russia's western Kursk region, in its first substantive remarks two days after Russian reports of a renewed Ukrainian thrust in the area.
