People shelter in Kyiv metro as Russia shells city

STORY: Moscow reacted with fury to the German and American announcements, and has in the past responded to apparent Ukrainian successes with air strikes that have left millions without light, heat or water.

The Ukrainian military said it had shot down all 24 drones sent overnight by Russia, including 15 around the capital, with no damage reported.

But soon afterwards, air raid alarms sounded across Ukraine as people were heading to work, and senior officials said air defences were shooting down incoming missiles.

Kyiv's military administration said more than 15 missiles fired at Kyiv had been shot down, but urged people to remain on shelters.
