The terrifying moment a Russian missile struck the building a Ukrainian blogger in Kharkiv was standing beside as he filmed a video for Instagram

An airstrike hit a building in the second-largest city of Kharkiv, while a person filmed a video for the photo-sharing website.

Nikita Demenkov spoke to the camera about how donations he had received had been used.

A sound can be heard overhead about 14 seconds into the video. The building in front of Demenkov is struck by a missile when he looks up to the sky.

Demenkov can be seen ducking as debris falls around him, and he runs to a basement to take cover.

Missiles have rained down across the country after Russia invaded Ukraine.

The predominantly Russian-speaking city of Kharkiv has been the target of heavy shelling and missile attacks.

Sky News reported that Constitution Square, one of the city's central squares, as well as a regional police department and a university, have been struck.
