Gunmen shot dead two Shia clerics in suspected sectarian violence overnight in a town 150 kilometres northwest of Multan, police said on Sunday. The attackers, believed to be Sunni militants, sprayed bullets at the clerics who were sleeping in the guesthouse of a Shia leader in the town of Chaubara, local police chief Rai Muhammad Tahir said. The clerics, who were visiting Chaubara, died on the spot while another guest, a Shia lawyer, was injured, he said. The attackers fled in a car.“It might be a sectarian attack because the slain men were visiting the town to collect donations to build a Shia madrassa (seminary) in the area,” he told reporters. “We are investigating the case,” he said adding that no one had been arrested so far. Shia leader Sajid Naqvi condemned the killings.
