Ten members of illegal armed groups have been killed in Chechen mountainous districts in an ongoing large- scale operation that was launched there several days ago, Chechen First Deputy Prime Minister Ramzan Kadyrov told Interfax on Saturday. "The examination of the bodies shows that they are Dagestanis, Chechens, and foreigners," Kadyrov said. "The guerilla unit currently numbers over 60 people, taking into account the losses it has suffered," Kadyrov said. "It is international by its composition and includes Arabs, Dagestanis, Azerbaijanis, and Chechens," he said. The operation against the guerilla unit led by prominent Dagestani- born terrorist Rappani Khalilov and Aslan Maskhadov's chief of staff Akhmed Advorkhanov was resumed on Saturday morning, Kadyrov said.
