KANDAHAR/KUNDUZ  - A roadside bomb killed 10 civilians, including a woman and five children, and wounded eight when it ripped through a van in southern Afghanistan on Thursday, officials said.The families were on their way to visit a relative who had recently returned from Makkah when their vehicle was hit in Dih Rawud district in rural Uruzgan province, district governor Nematullah Khaliqi told AFP. “Four of the dead are men, one is a woman and the rest are children. Eight others, men, women and children, are wounded,” he said. The death toll was confirmed by Abdullah Hemat, a spokesman for the provincial governor. Separately, two men were arrested for slitting the throat of a 15-year-old Afghan girl after her family refused a marriage proposal, police said Thursday. The girl was carrying water from a river to her village home in northern Kunduz province on Wednesday when she was murdered, police spokesman Sayed Sarwar Hussaini told AFP. “The two men attacked her and slit her throat with a knife,” he said. “They were arrested and are in police custody.” Hussaini said one of the suspects had proposed marriage to the girl but her family had rejected the offer.Extreme violence against women and girls remains a major problem in the country more than a decade after US-led troops brought down the notoriously brutal Taliban regime.According to figures by British charity organisation Oxfam, 87 per cent of Afghan women report having experienced physical, sexual or psychological violence or forced marriage.Last month a 20-year-old woman was beheaded by her husband’s family in the western province of Herat after she refused to become a prostitute, police said. Four people were arrested over the brutal killing.And in September, five people were arrested over the public flogging of a 16-year-old girl for allegedly having an affair.The girl was whipped 100 times in front of village elders and family members in central Ghazni province. Her alleged boyfriend was fined.
