After 100 days of war, about 20% of Ukraine's territory is now under Russian control, President Volodymyr Zelensky said, adding that the Donbas region is "almost completely destroyed."

Zelenksy said Ukrainian forces are resisting the Russian attack around the key eastern city of Severodonetsk, where some 800 people are hiding in bomb shelters under a chemical factory that was hit by Russian missiles.

Ukrainian forces say they have made significant progress during an offensive against Russian positions in the occupied southern region of Kherson.
