Pakistan ordered an investigation on Monday into the killing of five women who rights groups say were shot and buried alive because three of them wanted to marry men of their choice, reported reuters. The killings have produced shock and outrage even in a country inured to the murder of women by male relatives in the name of family honour in conservative, rural areas where tribal traditions hold sway. The women were killed in Babakot village, 320 km (200 miles) east of Quetta, capital of the southwestern province of Baluchistan, last month. The government's top Interior Ministry official, Rehman Malik, said he had ordered an inquiry headed by a top police officer and he wanted a report within a week. "We want facts," Malik said. "This isn't a European society. We're a different society but violence against women can't be tolerated either in the name of culture or religion," he said.
