The conflict has largely been a war of attrition, which requires large amounts of ammunition. Late on Sunday, Zelenskyy said the war is in “a very important phase” as the Ukrainian army works hard to hold the bigger Russian forces at bay in the east while also holding ground in Russia’s Kursk border region, which it captured two months ago.

Volodymyr Zelenskyy has said a formal invitation to join Nato is “the only way” Ukraine can survive Russia’s invasion, as the Ukrainian president urged western allies to endorse his plan to end the war.
