A Taliban militant was killed as his explosive device went off prematurely in the western Farah province, a statement of Interior Ministry released in Kabul on Tuesday said.

"A Taliban rebel was planting a mine on a road in Balablok district of Farah province Monday night but the device exploded prematurely, killing the rebel on the spot," the statement added.

Taliban militants who are largely relying on suicide and roadside bombings haven't made comment.
