Images of dead civilians in the streets of Bucha shocked the world and intensified concerns of Russian war crimes in Ukraine. Officials want more military aid, and bigger consequences for Russia.
The city, an island of relative safety surrounded by fighting, has become a hub for humanitarian aid and for people fleeing the war in the Donbas and other parts of Ukraine.
The Donbas region, the site of two breakaway republics created by Russia-backed separatists in 2014, has become the site of some of the heaviest fighting in recent days, a senior U.S. official says.
Thousands of Russians have left their country since their government began its invasion of Ukraine. Many have settled in Georgia, a country with a complicated history with its neighbor to the north.
