An activist of the group, who gave himself the name Escobar, said: The authorities claim that the cause of the explosion and the subsequent fire was a short circuit.

This is true, but only partially so.

"We made the short circuit. Our man put a switched on light bulb in a vessel with fuel lubricants. You know the rest," he added.

Escobar added: FSS is a symbol of falsehood and hypocrisy.

She is a pillar of the demonic power of Vladimir Putin.

Hitting it is more effective than setting fire to military districts and blowing up armed forces cars.

As the novini.bg team has already reported, on March 16, a powerful explosion shook the FSS building in the city bordering Ukraine.

"Black Bridge" unites about 1,500 supporters of anarchism.

The movement announced its existence in September 2022. Then it appealed to Russian citizens not to vote in the partial local elections.
