The Pakistani Taliban has extended a ceasefire with Islamabad in order to hold peace talks, two militant sources told Agence France-Presse on Wednesday. Since the Afghan Taliban surged back to power last year, its sister organization in Pakistan — Tehreek-e-Taliban Pakistan (TTP) — has stepped up attacks on state forces. Islamabad accuses the new Afghan authorities of harboring and emboldening TTP fighters along with militants from other groups who slip over the porous border to stage assaults. However, two militant sources told AFP that a TTP ceasefire agreed for the Islamic Eid festival had now been extended until May 16. A TTP letter outlining the truce, seen by AFP, tells fighters “not to violate the decision taken by the central command.” Both sources said a team of Pakistani mediators has traveled to Afghanistan to meet the TTP leadership for talks facilitated by the Afghan Taliban. Pakistan has not yet commented on the matter.
