International and Afghan forces killed 55 Taliban after coming under attack in southern Afghanistan, the United States military said on Wednesday. "ANSF (Afghan National Security Forces) and coalition forces responded with small arms, rocket-propelled grenade, heavy weapons and supporting fires, killing 55 militants," the US forces in Afghanistan said. Police had said earlier that 35 Taliban were killed in the fighting in the southern province of Uruzgan that started on Tuesday when about 100 Taliban had tried to attack a district centre, AFP reported. "More than 100 Taliban launched an attack to capture the district of Dih Rahwud. Our police bravely resisted and killed 35 Taliban whose bodies are left in the area," provincial police chief Juma Gul Hemat told AFP. "Three of our policemen were also martyred and nine others were injured in the fighting," he said, adding international military warplanes were called in to help. Meanwhile, foreign troops killed nine Afghan soldiers in a mistaken airstrike in the southeast of the country overnight, the Afghan Defence Ministry said on Wednesday.
