Six Taliban militants lost their lives and six others sustained injuries as their explosive device went off prematurely in the northern Kunduz province on Friday, Interior Ministry said in a statement released here on Saturday. "A dozen Taliban militants were busy in making roadside bomb in a house in Chardara district of Kunduz province on Friday evening but the device exploded accidently killing six rebels on the spot and wounding six others," the statement added. Taliban militants who are largely relying on suicide and roadside bombings have yet to make comment.
