On Sunday, a representative of the local administration told the AFP agency: “Clashes and attacks on the convoy on November 21, 22 and 23 resulted in the death of 82 people and 156 wounded.”
He said on condition of anonymity that 16 of the dead were Sunnis, and 66 belonged to the Shia community.
Women and children were among those killed in Thursday’s attacks on convoys. Passenger Saeed Bano told the BBC in Urdu how she feared she would be killed as she hid under the car seats with her children.
Hundreds of residents fled amid escalating violence on Friday and Saturday.
It comes after dozens of people have been killed in attacks over the past few months, prompting calls for a ceasefire from the tribal council.
On Saturday, provincial officials began talks with leaders of the Shia and Sunni communities, AFP reported.
A security official in the provincial capital Peshawar told AFP the negotiators’ helicopter had been fired upon as it arrived in the region.
