Ukraine invasion: What to know as Russian forces target Kyiv

Invading Russian forces are closing in on Ukraine’s capital, in an apparent encircling movement after a barrage of airstrikes on cities and military bases around the country

NICOSIA, Cyprus -- Invading Russian forces closed in on Ukraine's capital Friday, in an apparent encircling movement after a barrage of airstrikes on cities and military bases around the country.

With growing signs that Russia aims to overthrow him, Ukrainian President Volodymyr Zelenskyy told European Union leaders in a video link-up from his bunker late Thursday that it might be the last time they saw him alive.

But on Friday Zelenskyy released a video of himself and his senior aides outside the presidential office in Kyiv to reassure Ukrainians that he and other top officials would stay in the capital.

The assault, anticipated for weeks by the West, amounts to Europe's largest ground conflict since World War II as President Vladimir Putin tries to restore Moscow's Cold War influence. It is unclear how much or little Russian forces have seized or the extent of the casualties.
