Russia's deputy emergencies minister, Yuri Brazhnikov, said in Moscow that these "technicians" - thought to be soldiers - would begin working on "humanitarian" tasks, including mine clearance and aid delivery. "We need to . . . establish what specifically the Afghan population needs," he said. The advance Russian group, due to expand to a total of 200, "will most likely work on a permanent basis, while its members will rotate", said Mr Brazhnikov.
