Morning dawns on Ukraine's Black Sea port of Odesa

Dawn broke on Saturday in Ukraine's Black Sea port of Odesa as Russia's invasion of the country continued. Earlier, Russian troops stormed towards Kyiv and street fighting broke out as city officials urged residents to take shelter.

The country's president Zelenskyy refused an American offer to evacuate, insisting that he would stay. "The fight is here," he said. The clashes followed two days of fighting that resulted in hundreds of casualties and pummeled bridges, schools and apartment buildings.

The invasion of Ukraine began early on Thursday with missile strikes on cities and military bases, followed by a multi-pronged ground assault that rolled troops in from separatist-held areas in the east; from the southern region of Crimea, which Russia annexed in 2014; and from Belarus to the north.
