Sri Lanka’s air force bombed a major eastern rebel base for the third straight day Wednesday, the Defence Ministry said, as Amnesty International said armed groups - some wearing breakaway Tamil Tiger insurgent uniforms - are abducting people from refugee camps. Details of casualties and damage from the air raid on the mainstream Tamil Tigers’ Thoppigala base in Sri Lanka’s eastern jungles were not immediately known. The base has served as a major training centre for the rebels. It is considered one of the last rebel redoubts in the east, since Sri Lankan forces have carried out several ground and air attacks over the past year and captured other territory. “This morning we have taken a target there,” military spokesman Brig Prasad Samarasinghe told reporters. A rebel spokesman confirmed the air raid, but said the insurgents suffered no casualties. “The bombs fell in the jungle areas and none of our fighters were there,” said Rasiah Ilanthirayan from the mainstream insurgents’ stronghold of Kilinochchi.
