Ukraine's emergency service released footage on Thursday (May 29) showing firefighters extinguishing a large fire after Russian drones hit Sumy region.

Reuters was not able to confirm the location and date when the video was recorded.

Ukrainian authorities regularly report Russian drone and aerial bomb attacks on Sumy region.

After Russia said in late April it had ejected Ukrainian forces from the western Kursk region, Moscow's forces have pushed over the border into the neighbouring Sumy region of northeastern Ukraine and taken several villages there.

Ukrainian President Volodymyr Zelenskiy said on Tuesday (May 27) that Russia has gathered 50,000 troops near the northern Sumy region, but added that Kyiv had taken steps to prevent Moscow from conducting a large-scale offensive there.
