US-led coalition and Afghan soldiers "routed" a large number of Taliban fighters in a two-day battle in southern Afghanistan's poppy-growing heartland, killing more than 50 suspected militants, the coalition said Monday. The battle in Helmand province's Sangin district saw the insurgents attempt to shoot down a coalition aircraft and attack soldiers with a suicide car bomb, the coalition said in a statement. Coalition aircraft dropped four bombs during the engagement, and Afghan forces counted "more than four dozen" insurgents killed, it said. The Sangin district chief, Eizatullah Khan, said a big group of Taliban had attacked a convoy of vehicles Sunday afternoon. He said the battle left more than 30 Taliban dead and many wounded.
