Twenty-nine people were reported killed in an unprecedented attack on a refugee camp in the north-west of the Sudan region of Darfur, the United Nations said yesterday. According to initial reports, the Aro Sharow camp was attacked by 250-300 "armed Arab men on horses and camels" late on Wednesday, the UN High Commissioner for Refugees (UNHCR) said in a statement. Another 10 people were reported to have been seriously wounded and the nearby village of Gosmeina was also believed to have been attacked and burned, the agency said. The death toll referred only to camp dwellers. The camp, home to between 4,000 and 5,000 people, lies 16 km north of the town of Saleah in an area that has been regarded as a no-go zone for the UN for months because of continuing violence.
