SADDA (Agencies) Several Nato fighter jets violated Pakistans airspace over in Kurram Agency on Friday, causing panic among the locals. According to locals, the Nato aircraft crossed over into Kurram Agency through the Afghan border and flew up to five-kilometres across the border. The planes returned back to Afghanistan after a few minutes without any incident. They went over Pakistani territory for a few minutes before returning to Afghanistan. NATO helicopters entered the same region last year, firing several rockets that killed three Pakistani soldiers. The incident forced Islamabad to shut the Nato supply route that traverses Pakistan, suspending the delivery of goods to foreign troops in Afghanistan. Tensions between the two countries increased following a secret US raid on Pakistan in May that allegedly killed Al-Qaeda leader Osama bin Laden.
