A recently formed bloc of the Pakistani Taliban announced its split from the group's official leadership Thursday, pledging its loyalty to a brash young commander linked to a series of brazen attacks. The move indicates a deepening shift away from Maulana Fazlullah. The new bloc, named the TTP Jamat-ul-Ahrar (freedom fighters group) is headed by Omar Khalid Khorasani, whose fighters announced in February they had executed 23 Pakistani paramilitaries held since 2010.
