In September 2004 Basayev claimed responsibility for the Beslan school siege in which over 350 people , most of them children , were killed and hundreds more injured . The Russian government put up a bounty of 300m rubles ( $ 10m ) for information leading to his capture . Basayev himself did not participate in the seizure of the school , but claimed to have organized and financed the attack , boasting that the whole operation cost only 8,000 euros . On 17 September 2004 , Basayev issued a statement claiming responsibility for the school siege , saying his Riyadus-Salihiin " Martyr Battalion " had carried out this and other attacks . In his message , Basayev described the Beslan massacre as a " terrible tragedy " and blamed it on Russian President Vladimir Putin
