At least 20 militants and five soldiers were killed in clashes with government forces for control of a strategic road tunnel in Pakistan's restive tribal area, the army said Sunday. The militants captured the Friendship tunnel on the Indus Highway, which links North-West Frontier Province with southern and central Pakistan, near the tribal town of Darra Adam Khel on Friday evening by killing five troops and seizing ten more at a nearby security check post. "Helicopter gunships targeted insurgents' position in the mountains near the tunnel last night. Around 20 miscreants were killed in the action," said military's chief spokesman Major General Athar Abbas, according to a report of DPA.
