Explosions have rocked several Ukraine cities after Russian President Vladimir Putin declared a special military operation in the country's east.
It appears to be much more than that with Ukrainian officials calling it a full scale war saying the Russian invasion had begun.
CNN correspondent Atika Schubert is in the city of Lviv, about 500km west of Kyiv.
Sirens are going off in Kyiv. The mayor has urged citizens to stay home after explosions were heard in the city.
That message seems to have been heard. The streets appear deserted.
