KARACHI - The long disappearance of the Ameer of Tehreek-e-Taliban Pakistan (TTP), Baitullah Mehsud, from the scene has raised many eyebrows that whether he is alive or not. Mehsud came into limelight when tribal leader Naek Mohammad was killed by the security forces during a missile attack and he (Mehsud) also found involved in attacking on Pakistan Army installations. Well-informed sources told The Nation that the months long disappearance of the top Pakistani Taliban commander were casting doubts over his deteriorating health.   However, an insider said that Baitullah Mehsud was disappeared after massive operation was launched by the Pakistan Army against the banned outfits. His disappearance gripped the religious circles that he might be dead during the fall of Baghazai village in fighting with the Toori tribes of the Kurram Agency who captured the control of Baghazai, a month ago, from the custody of Taliban Pakistan. Insiders said that after US incursion in tribal belt, no statement had been issued by Baitullah Mehsud. After the Lal Masjid operation, he openly declared war against the Pakistan Army and suicide bombings were also increased. Previous govts made several peace deals with Baitullah Mehsud to maintain peace in tribal areas but it was broken by Baitullah Mehsud and on many occasions hostage Army soldiers and also attacked on their installations. Mehsud who is leading the religious insurgency in tribal belt is most wanted to Pakistani government and US who not only involved in attacking on Pakistan forces but also involved in attacking Nato forces in Afghanistan. Baitullah and Abdullah Mehsud, hailing from the powerful Mehsud tribe of Pushtuns, parted their ways soon. Abdullah, whom Baitullah suspected of being a double agent, was killed in a shootout last year in Zhob district of Balochistan on the Afghan borders. His death left Baitullah the sole contender of command in the troubled South Waziristan and its vicinities. Mehsud is the biggest tribe in South Waziristan with 60 per cent of the 700,000 population while its rival Wazir tribe makes up 35 per cent. The assassination of some 400 pro-government tribal lords, mostly belonging to Wazir tribe, last year is the major bone of contention between the two powerful tribes. Baitullah Mehsud had never got education from any school or seminary. Militants considered him a natural leader with keen political instincts of waging war against US occupied forces in Afghanistan.   Mehsud, believes to be around 35, is suffering from diabetes and is on permanent treatment. "Despite the fact that he is a diabetic, he is a very active man. He rarely talks to newsmen. And whenever he meets local journalists, his face remains covered," as reported in media.
