Ukraine invasion: What to know as Russian forces target Kyiv

Invading Russian forces have set their sights on Kyiv, positioning themselves in what appears to be encircling movement around the Ukrainian capital

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.

Ukrainian President Volodymyr Zelenskyy told somber European Union leaders in a video link-up from his bunker late Thursday that it may be the last time they see him alive.

Pre-dawn explosions rocked Kyiv, and gunfire was reported in parts of the city, while Ukraine's military said a group of Russian spies and saboteurs was seen on the capital's outskirts. Police told people not to exit a central subway station because of gunfire.

The assault, anticipated for weeks by the West, amounts to Europe's largest ground conflict since World War II. It could also portend the emergence of a new “Iron Curtain” between the West and Russia, with global repercussions.
