An adviser to Ukrainian President Volodymyr Zelenskiy said on Wednesday that Russia had not captured Kherson, a southern port city that Russia had earlier said it had seized.
Oleksiy Arestovych said fighting continued for the provincial capital of around a quarter of a million people, which sits at the Dnipro river's exit into the Black Sea.
"The city has not fallen, our side continues to defend," Arestovych told a live briefing broadcast on the website of the president's office. "Fighting in the streets continues."
"Information that Kherson has fallen and so on - that's not true. Our military and local defenders continue resisting in the city and around it."
