The Taliban announced on Sunday that it will not extend a three-day ceasefire in Afghanistan, saying the fighting will resume. "The ceasefire ends tonight and our operations will begin. We have no intention to extend the ceasefire," spokesman Zabihullah Mujahid told AFP in a WhatsApp message. His comments come after Afghan President Ashraf Ghani announced Saturday a government truce with the militants would be extended. He asked the group to reciprocate. The first formal, nationwide ceasefire in the country since the 2001 US invasion had been met with jubilation across the country as Afghans -- Taliban, security forces and civilians -- celebrated Eid, the holiday that caps the fasting month of Ramadan. Later on Sunday, Najibullah Kamawal, director of the health department in the eastern Nangarhar province, announced that the death toll from a suicide bombing against a gathering of Taliban fighters celebrating the ceasefire had risen to 36. Another 65 people were wounded in Saturdays attack. No one immediately claimed the attack, but it was likely carried out by the ISIS group, which was not included in the ceasefire and has clashed with the Taliban in the past.
