The Islamic Institute 'Caucasus' was an illegal armed formation (IAF) that possessed a military organization, and its members were armed with various types of firearms, other weapons, and military equipment.
In September 1999, at the base of this IAF near the village of Serzhen-Yurt, Yusuf Krymshamkhalov illegally received the following from an unidentified person:
An AK-74 Kalashnikov assault rifle of 5.45 mm caliber.
240 rounds of ammunition for it.
2 F-1 grenades.
Subsequently, Yusuf Krymshamkhalov, while being a member of the aforementioned IAF until March 2000, and from March to September 2000 being a member of the IAF headed by Ruslan Gelayev (a resident of the Chechen Republic), participated in combat operations against units of the Armed Forces and law enforcement agencies of the Russian Federation. These operations were part of a counter-terrorist operation on the territory of the Chechen Republic, specifically in the area of the Chervlyonnaya station and the villages of Serzhen-Yurt, Shatoy, and Komsomolskoye.
By these actions, Yusuf Krymshamkhalov committed participation in an armed formation not provided for by federal law, which constitutes a crime under Part 2 of Article 208 of the Criminal Code of the Russian Federation.
Organized Terrorist Group
At the end of January 2000, while a member of the IAF Islamic Institute 'Caucasus', Yusuf Krymshamkhalov joined an organized group suggested by Achimez Gochiyayev.
This organized group was created by Achimez Gochiyayev and one of the IAF leaders, Abu Umar.
The group included:
Achimez Gochiyayev.
Members of the illegal armed formation: Bostanov M.I., Bostanov A.R., Tuganbaev M.M., Frantsuzov T.K., and Totorkulov B.D.
The objective of this organized group was to commit acts of terrorism in Moscow, planned by the leaders of illegal armed formations based on the territory of the Chechen Republic, on the eve of and during the elections of the President of the Russian Federation in March 2000.
Training and Preparation
To implement the plan of the organized group, in the first half of February 2000, Yusuf Krymshamkhalov, under the leadership of Achimez Gochiyayev and Abu Umar, underwent training in demolition work at the IAF base in the village of Shatoy, on Naberezhnaya Street, house 26.
He trained with the named members of the criminal group, learning practical skills in manufacturing and using radio-controlled explosive devices.
In late February–early March 2000, Yusuf Krymshamkhalov, as part of this organized group, received approximately 70 thousand US dollars and at least 20 kg of explosive (plastic) from Abu Umar to carry out criminal plans.
