More than 80 people have been killed in renewed sectarian violence in north-west Pakistan, officials say.
Another156 are said to have been wounded in three days of fighting in the tribal district of Kurram, near the Afghan border.
The violence began on Thursday, when gunmen attacked convoys of Shia Muslims travelling through the area under police escort. More than 40 died in that incident, which triggered revenge attacks.
Shia and Sunni Muslims have engaged in tribal and sectarian rivalries over land disputes for decades.
