Tehrik-i-Taliban 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.
The TTP is not directly affiliated with the Afghan Taliban movement led by Mullah Omar, with both groups differing greatly in their histories, strategic goals and interests although they are both predominantly Pashtun. The Afghan Taliban, with the alleged support of Pakistani Taliban, operate against international coalition and Afghan security forces in Afghanistan but are strictly opposed to targeting the Pakistani state. The TTP in contrast has almost exclusively targeted elements of the Pakistani state although it took credit for the 2009 Camp Chapman attack and the 2010 Times Square car bombing attempt. On 16 December 2014, the TTP attacked a school in Peshawar, killing over 140 people including 132 children. TTP officials claimed responsibility for the attack as a response to the Pakistani military’s offensive in northeastern Pakistan’s tribal areas, an action that has killed hundreds of militants.
Maulana Fazlullah became the group's new leader in late 2013. In the following year the TTP fragmented into at least four groups, with the defections said to have left the group in considerable disarray.
