Kyiv under siege
Russia pressed its invasion of Ukraine to the outskirts of the capital on Friday after unleashing airstrikes on cities and military bases and sending in troops and tanks from three sides in an attack that could rewrite the global post-Cold War security order.
Explosions sounded before dawn in Kyiv and gunfire was reported in several areas, as Western leaders scheduled an emergency meeting and Ukraine's president pleaded for international help to fend off an attack that could topple his democratically elected government, cause massive casualties and ripple out damage to the global economy.
The Russian military said it had seized of a strategic airport just outside Kyiv and the city off from the west. The Ukrainian military, meanwhile, said a group of Russian spies and saboteurs was seen in a district on the outskirts of Kyiv, and police told people not to exit a subway station in the city center because there was gunfire in the area.
Elsewhere in the capital, soldiers established defensive positions at bridges, and armored vehicles rolled down the streets, while many residents stood uneasily in doorways of their apartment buildings.
US Secretary of State Antony Blinken said Kyiv "could well be under siege" in what US officials believe is a brazen attempt by Russian President Vladimir Putin to install his own regime. The assault, anticipated for weeks by the US and Western allies, amounts to the largest ground war in Europe since World War II.
