Anti-Putin Group Claims Responsibility for Deadly Fire at Russian FSB Compound.

Russian anti-Putin group Black Bridge has claimed responsibility for a fire at a building used by the Federal Security Service (FSB) in Rostov-on-Don, near the Ukraine border. The FSB said fuel and lubricants caught fire in a workshop, causing an explosion and partial collapse of the building. Black Bridge said the fire was caused by an improvised explosive device placed in a container of fuel. The group opposes Putin, Russian authorities and the war in Ukraine, and has claimed responsibility for attacks within Russia. Its ultimate goal is "violent resistance and the destruction of the Putin regime as a whole."
