A terrorist attack with the use of strong poisons was prevented in the North Caucasus. The cache with poisons was discovered on the Chechen-Ingush border. Two terrorist leaders were put on the wanted list, a spokesman for the Regional Operative Headquarters (ROH) for the counter-terrorist operation in the North Caucasus reported on Wednesday. One of them is Abu Mujaid, supposedly a Jordanian citizen, the emissary of the Moslem Brothers and Al Qaeda terrorist organizations in Chechnya and Ingushetia.The other is Russian citizen Alash Daudov, 35. According to the law enforcement bodies, he was involved in the terrorist attack on the Dubrovka theater center in Moscow in October 2002 when terrorists seized over 900 hostages (130 of them were killed). Moreover, Daudov participated in attacks on Ingushetia in June 2004 and on the Chechen capital in August 2004. In September 2004 Alash Daudov took part in preparations for the terrorist attack on the school in Beslan (North Ossetia). This barbaric crime left 330 people, including 176 children killed. According to the ROH spokesman, terrorists intended to use two types of poison. One of them is a cyanide poison and the other is still unknown. Experts believe that the use of minimal doses of these poisons in public places could have led to many victims. Chechen terrorist leader Shamil Basayev and Abu Mujaid are suspected of being the masterminds of the poison attack. Alash Daudov was supposed to perpetrate the terrorist act.
