Russian authorities have declared a state of emergency in Kursk, a border region where Ukrainian forces have launched a dramatic surprise attack that Kyiv and its closest partners hope will inaugurate a new phase of Russia’s war in Ukraine.

“Russia brought the war to our land, and it should feel what it has done,” Ukrainian President Volodymyr Zelensky said Thursday. “We strive to achieve our goals as soon as possible in peacetime – under just peace conditions. And it will happen.”
