KABUL, Afghanistan — U.S.-led forces raided a Taliban bomb-making cell in eastern Afghanistan, killing 32 insurgents in a battle with scores of armed militants who shot at them from rooftops and alleyways, the military said Wednesday.

The firefight broke out Tuesday in Laghman province when as many as 75 armed militants converged on the troops, who were searching a number of compounds in the area, the military said in a statement. The 32 insurgents were killed when coalition troops returned fire.
