Zelenskyy: Ukraine fighting for 'every meter' of Severodonetsk
Russian forces have pushed the Armed Forces of Ukraine out of the center of Severodonetsk, Ukrainian officials said.
"They are pressing in Severodonetsk, where very fierce fighting is going on -- literally for every meter," Ukrainian President Volodymyr Zelenskyy said in an address on Sunday evening.
Russian forces now control about 70% of the city, as intense shelling makes mass evacuation and the transportation of goods impossible, Sergiy Haidai, another Ukrainian official, said.
Around 500 people, including 40 children, are sheltering in the city's Azot chemical plant, Haidai said.
While the Ukrainians try to organize their evacuation, authorities of the self-declared Donetsk People's Republic have given an ultimatum to Ukrainian troops in the city.
"They have two options: either follow the example of their colleagues and give up, or die. They have no other option," said Eduard Basurin, deputy head of the People's Militia Department of the DPR.
