(Xinhua) -- Gunmen wearing military uniforms stormed a village near the Iranian border and killed 15 people on Saturday, a local official said. "Some 50 militants in three trucks wearing Iraqi army uniform stormed the Hameed village, just south of the town of Mandily, some 110 km northeast of Baghdad, killing 15 people and wounding a woman," Jawad Kadhim al-Bazaz, deputy mayor of Mandily in Diyala province, told Xinhua by telephone. Residents of the village said that the gunmen claimed they were on a legitimate mission and searched the houses for weapons and wanted insurgents, but they ordered the people to leave their houses and separated men from the women and children and then they shot at the men, Bazaz said. "Most of the killed people are from Iranian origin families who returned to Iraq after the U.S.-led invasion. They were forced to leave Iraq on the year 1975," he said. Bazaz blamed the attack on militants from the al-Qaida in Iraq who have a strong presence in the volatile Diyala province.
