Russia has begun to evacuate residents from the border region of Belgorod following a surge in deadly Ukrainian strikes, in a rare admission of the dangers posed by a war from which Moscow has sought to isolate its citizens.

Approximately 300 residents of Belgorod city “decided to temporarily move” to accommodation centers in cities elsewhere in the region, governor Vyacheslav Gladkov said Monday.

Gladkov on Friday offered to help any Belgorod residents worried by the recent spate of Ukrainian attacks on the region, which borders northeastern Ukraine.
