Suspected militants shot dead a pro-government tribal elder, while separately three others were gunned down in a Pakistani tribal zone bordering Afghanistan, officials said on Sunday.
Malik Wali Zar, a member of a government-sponsored committee, working on expulsions of foreign pro-Taliban militants, was shot dead on Saturday at Inzar village in South Waziristan tribal district, a security official said.
Zar was returning home after attending a meeting in Wana, the main town of South Waziristan, when he was dragged from a passenger van by masked gunmen and shot dead, a security official told AFP.
Several tribal elders have been murdered this year for supporting Pakistan's campaign against al Qaeda and other militants in the area.
Separately, unidentified gunmen shot dead three tribesmen in neighbouring North Waziristan tribal district on Saturday, another security official said.
The three were hauled from a van in Dangeen village, North Waziristan, and shot dead. The attackers then fled in a waiting car, he said.
It was not immediately clear whether pro-Taliban militants were behind the attack, the official said, adding an investigation had been launched. In another incident, senior local administration official Faiz Ullah was travelling in a passenger van when he was kidnapped by armed gunmen in the town of Mir Ali on Sunday, the official said. The government signed a peace deal with tribal elders in North Waziristan early September, under which al Qaeda and Taliban fighters would be expelled from the area.
