Multiple Fires and Explosions at Russian Security Buildings in Rostov-on-Don.

A building for the border patrol of Russia’s Federal Security Service (FSB) caught fire in Rostov-on-Don, killing at least one person and injuring two. The FSB is Russia’s main domestic security service, responsible for border security, surveillance, and counterterrorism. Local residents heard loud explosions before the fire broke out. The cause of the fire is believed to be a short circuit that ignited fuel tanks. The incident occurred amid rising concern about sabotage by groups opposed to Russia’s invasion of Ukraine.
