More than 80 people have been killed in renewed sectarian violence in northwest Pakistan, officials say.
Another 156 were reportedly injured during three days of fighting in the Kurram tribal district near the Afghan border.
The violence began on Thursday, when gunmen attacked convoys of Shiite Muslims passing through the area under police escort. More than 40 people died in the incident, which sparked reprisals.
Shiite and Sunni Muslims have engaged in tribal and sectarian rivalries over land disputes for decades.
On Sunday, a local administration official told the AFP news agency: “The clashes and attacks on convoys of November 21, 22 and 23 left 82 dead and 156 injured.”
Speaking on condition of anonymity, he said 16 of the dead were Sunnis and 66 were from the Shiite community.
Among those killed in Thursday's attacks on convoys were women and children. Passenger Saeeda Bano described to BBC Urdu how she feared being killed as she hid under the car seats with her children.
Hundreds of residents fled Friday and Saturday in the face of escalating violence.
It comes after dozens of people died in attacks in recent months, prompting a tribal council to call for a ceasefire.
On Saturday, provincial officials began talks with leaders of the Shiite and Sunni communities, AFP reported.
A security official in Peshawar, the provincial capital, told AFP that the negotiators' helicopter came under fire when it arrived in the region.
