WANA: Four people were killed on Wednesday in a mine blast targeting the vehicle of a pro-government tribal elder in South Waziristan Agency, officials said. The elder, Haji Khadeen, who had led a government campaign against Al Qaeda-linked insurgents, was critically wounded while three of his relatives and a passer-by died. The attack took place in Dazha Ghandi. âAccording to our information, four people died when the vehicle hit a mine planted by unidentified people,â local administration official Wasal Khan said. âHaji Khadeen is in hospital, his condition is serious.âIt was not immediately clear whether the mine blast was part of a tribal vendetta or linked to Khadeenâs role in the campaign against militants in the region, officials said. Witnesses said members of Khadeenâs clan later opened fire and threw grenades at a Wana market shopping plaza owned by rival tribesmen, but no casualties were reported. This year Khadeen had raised a tribal force that conducted house-to-house searches after the Pakistan Army launched an operation against Islamic insurgents in March. No one was arrested in the search operation but the lashkar (tribal army) destroyed several houses on suspicion their inhabitants were sheltering foreign militants.
