An apartment complex in Kyiv caught fire after missile fragments fell on the 14-story building during a Russian strike on the Ukrainian capital on Sunday morning.

Residents on Monday were seen cleaning up the mess left by the debris from a missile shot down by Ukrainian forces the day before. The area was scattered with broken window glass.

Authorities in the city of Kyiv said in a social media post on Sunday that Russian forces are trying new tactics, because hitting the capital is one of their highest priorities. They said Russia is in search of the right time, methods and means to hit Kyiv.

The authorities called on people to seek shelter whenever sirens sound, since fragments of shot-down missiles could threaten human lives.
