Russia’s FSB security service said Monday that four people arrested over a foiled “terror” plot had provided money and arms for the deadly attack on a Moscow concert hall last month.
More than 140 people were killed when gunmen stormed the Crocus City Hall venue on March 22 before setting the building on fire in the most deadly attack in Russia for two decades.
The FSB said in a statement Monday that it had arrested four people a day earlier in the southern Dagestan region who “were directly involved in the financing and supply of terrorist means to the perpetrators of the terrorist act carried out on 22 March in the Crocus City Hall in Moscow.”
Russia’s national anti-terrorism committee said on Sunday that it had apprehended three people who were “planning to commit a series of terrorist crimes.”
The FSB said Monday that four foreign citizens had been arrested in the operation in the regional capital Makhachkala and the nearby town of Kaspiysk.
The Interfax news agency cited an FSB video showing one of the detained men saying: “I took weapons to them, these guys who attacked Crocus City Hall. I took them weapons from Makhachkala.”
Russian authorities had previously announced the arrests of 12 people they say are connected to the attack—including the four suspected gunmen, who have been identified as Tajik citizens.
