Zelenskyy vows to keep up resistance
As Russian troops advance on Kyiv, Ukrainian President Volodymyr Zelenskyy has said he will remain in the city and was not giving up.
"We will not put down weapons; we will defend our state," he said in a video filmed outside his office Saturday morning.
Zelenskyy had earlier rejected an offer from the US to take him to safety. "The fight is here,'' he said. The Ukrainian leader has described himself as a "main target" for Russia.
