Which is NOT true about the attack?

Chechnya’s main rebel group denies it was behind Monday’s attack on government buildings in the neighboring Republic of Ingushetia.  At least fifty- seven people died including the Ingush interior minister. The deputy leader of the rebels Akhmed Dzigaryav told the Reuters News Agency Tuesday his group did not lead or plan the attack. But he said he is certain other Chechen rebels took part. He said the attackers were led by an Ingush commander he called Magmand. Mr. Dzigaryav said what he calls the lawlessness and destruction of Russian forces in Ingushetia brought about the attacks.
