MANILA, Philippines (AP) — A battle between Philippine marines and Muslim militants, who launched a surprise attack to regain control of a captured jungle training encampment, has left 14 Abu Sayyaf fighters and one marine dead, officials said Wednesday.

The heavy exchanges of rifle grenade and mortar fire erupted late Tuesday in a mountain area off southern Sulu province’s Patikul town then eased into sporadic exchanges of sniper shots past midnight, with reinforcement marines beating back about 100 Abu Sayyaf attackers, military officials said.
