Ukraine refugee count reaches 2 million as safe corridors are opened for evacuation

More than 2 million refugees from Ukraine have fled to neighboring countries in response to the Russian invasion, according to United Nations officials.

The latest tally comes well into the second week of the Russian invasion and follows previous efforts to evacuate Ukrainian civilians from the southern port city of Mariupol who were struggling amid the Russian attack.

Video posted Tuesday by Ukrainian officials showed buses with people moving along a snowy road from the eastern city of Sumy and yellow buses with a red cross on them in the southern port of Mariupol.
