Tehrik-i-Taliban Pakistan (TTP; Urdu: ; "Taliban Movement of Pakistan"), alternatively referred to as the Pakistani Taliban, is an umbrella organization of various Islamist militant groups based in the northwestern Federally Administered Tribal Areas along the Afghan border in Pakistan. Most, but not all, Pakistani Taliban groups coalesce under the TTP. In December 2007 about 13 groups united under the leadership of Baitullah Mehsud to form the Tehrik-i-Taliban Pakistan. Among the Tehrik-i-Taliban Pakistan's stated objectives are resistance against the Pakistani state, enforcement of their interpretation of sharia and a plan to unite against NATO-led forces in Afghanistan.
