Riyad-us Saliheen Brigade of Martyrs
Riyad-us Saliheen (Russian: Риядус-Салихийн, also transliterated as Riyadus-Salikhin, Riyad us-Saliheyn or Riyad us-Salihiin) was the name of a small "martyr" (shahid) force of suicide attackers. Its original leader (amir) was the Chechen separatist commander Shamil Basayev. In February and March 2003, the group was designated by the United States and subsequently by the United Nations as a terrorist organization. After several years of inactivity, Riyad-us Saliheen was reactivated by the Caucasus Emirate in 2009 under the command of Said Buryatsky; following his death, Aslan Byutukayev became its new leader.
