Islamabad— Pakistani authorities have brokered a seven-day ceasefire following intense sectarian violence in the northwestern Kurram tribal district near the Afghan border. Over three days of clashes, 82 people were killed and 156 injured, according to local officials.

The violence erupted on Thursday when gunmen attacked convoys of Shia Muslims under police escort, killing over 40 people, including women and children. Revenge attacks quickly escalated, forcing hundreds of residents to flee.

Negotiations between Shia and Sunni leaders, facilitated by government officials, led to the ceasefire agreement on Sunday. Muhammad Ali Saif, a government spokesman, confirmed both sides agreed to halt hostilities.

The conflict stems from longstanding sectarian and tribal disputes over land. Survivors described harrowing experiences, with families hiding in mountains amid freezing temperatures. A tribal council had urged an end to the violence, prompting the talks.

Security remains tight in the region, with officials monitoring the fragile truce.
