A Russian partisan group called Chyorny Most (Black Bridge) has claimed responsibility for a fire in the compound of the Federal Security Service (FSB) in the Russian city of Rostov-on-Don near the Ukrainian border that killed at least four people and injured five others on March 16. The group said on Telegram on March 21 that it was “a co-author” of the incident by contributing to its preparations and implementation. It did not name any others involved. Black Bridge positions itself as a guerrilla movement fighting against President Vladimir Putin and Moscow’s full-scale aggression against Ukraine.
