President Volodymyr Zelenskyy says he will urge allies to boost Ukraine’s air defenses at a meeting this week in Germany, while both sides said Kyiv’s forces pressed new attacks Sunday in Russia’s Kursk region.

Russia said on Sunday that Ukraine had launched a counter-attack in the Kursk region, an area of western Russia from which Russian troops have been trying to eject Ukrainian forces for the past five months.

Russia said Sunday that Ukraine had launched a "counterattack" in the western border region of Kursk, where Kyiv's forces began a shock ground offensive last August. It was not immediately clear how much Ukraine had advanced in the region, but pro-Kremlin military bloggers reported earlier that a powerful new offensive was under way.

Russian forces continue to make costly but consistent gains in the Donetsk region in eastern Ukraine. They are steadily grinding down a pocket of resistance around the town of Kurakhove in the southern Donbas region and are also fighting to envelop the larger city of Pokrovsk to the north, Ukrainian soldiers and officials said.
