ISLAMABAD - The process of identification of the key TTP leader Maulvi Faqir Mohammad by Afghan forces on February 21 has further deepened the mystery, sources said on Sunday.

Well-placed sources told TheNation that Pakistani authorities were at loss to understand the logic being given by the Afghan government about the identification of the militant.

Faqir and his four accomplices who had entered Nangarhar from Bajaur Agency were apprehended near Basawal on Torkham Road near the border of Khyber Agency's Tirah Valley.

Afghan Foreign Minister personally confirmed capturing of Maulvi Faqir Mohammad to his Pakistani counterpart Hina Rabbani Khar very next day and assured her that he would soon be handed over to Pakistan.

Maulvi Faqir was the deputy ameer (second-in-command) of the Tehrik-i-Taliban Pakistan (TTP) and the Taliban chief in Bajaur Agency, but was later removed from his position in March 2012 on suspicions of entering into a peace deal with the Pakistani government.

Faqir Muhammad, who hails from Chopatra Village of Bajaur Agency, was first part of the Tehreek-i-Nifaz-i-Shariat-i-Muhammadi, and later the deputy chief of TTP until March 2012 when he had announced himself as the TTP chief after the death of Baitullah Mehsud.

Faqir had also publicly accepted his ties with al-Qaeda network and had been accused of a number of cross-border attacks in Bajaur Agency and the settled Lower and Upper Dir district.
