Kyiv Mayor Vitaly Klitschko on Thursday announced an overnight curfew in Ukraine's capital as the country battled to repel a Russian invasion.
The former world heavyweight boxing champion said the curfew would last from 10:00 pm to 7:00 am local time (2000-0500 GMT) and that public transport would stop working during that period.
Metro stations would remain open throughout to serve as bomb shelters, he said.
