Maulana Fazlullah, the chief of Taliban in Pakistan's Swat valley, has claimed that he fled to Afghanistan after evading troops conducting operations against militants and threatened to launch hit and run attacks soon against security forces in the restive northwest region. Fazlullah told BBC Urdu on phone that he has arrived in Afghanistan safely. He demanded that the Pakistan Army should act to stop US drone attacks in the country's tribal belt .Fazlullah also warned that North West Frontier Province Information Minister Mian Iftikhar Hussain will meet the same fate as that of former Afghan President Najibullah.The Taliban had hanged Najibullah and his brother after they captured Kabul in 1996. Fazlullah said there is no need for US President Barack Obama to send more troops to Afghanistan as hundreds of thousands of Pakistani forces are fulfilling the objectives of the Americans in their own country. The Pakistani military and federal ministers had claimed on several occasions that Fazlullah was injured during the anti-Taliban operations in Swat and surrounded by security forces.Meanwhile, Taliban militants have blown up a girls' school in Pakistan's Khyber district, the third such attack in the tribal region bordering Afghanistan so far this month. An intelligence official in the area said Taliban attacked the government-run school overnight when no one was at the property. The incident took place at Yousaf Kely village near Bara town, south of Peshawar. Islamist militants have destroyed hundreds of schools, mostly for girls, in the northwest of the country in recent years.
