The head of Russia's security agency says it has arrested three alleged Islamic militants suspected of organizing a suicide car bombing in Russia's volatile south.
The attack in the city of Vladikavkaz in Russia's province of North Ossetia left 19 dead and more than 200 wounded in early September. A Chechen rebel group has claimed responsibility for the bombing.
The Federal Security Service chief Alexander Bortnikov said in televised remarks Tuesday that the organizers were arrested in late September in the neighboring province of Ingushetia. He said two other suspects were killed by security forces.
The North Caucasus region has been gripped by almost daily violence stemming from two separatist wars in Chechnya and fueled by poverty and corruption.
