Clashes and attacks on convoys on November 21, 22 and 23 left 82 people dead and 156 wounded, a local administration official told AFP on Sunday.
He, who spoke on condition of anonymity, said 16 of the dead were Sunni and 66 were Shiite.
Those killed in Thursday’s convoy attack included women and children. Passenger Saeeda Bano described to BBC Urdu how she feared she would be killed while hiding under her car seat with her children.
Hundreds of residents fled as violence escalated on Friday and Saturday.
This comes after the tribal council called for a ceasefire after dozens of people have been killed in attacks in the past few months.
AFP reported on Saturday that local officials had begun talks with Shia and Sunni community leaders.
A security official in the provincial capital Peshawar told AFP that the negotiating team’s helicopter was attacked as soon as it arrived in the area.
