Rebels in Sudan's western region of Darfur said a government warplane killed eight civilians, mostly children, in a northern village on Monday. Sudan's armed forces said the report was a fabrication designed for propaganda purposes. Jarennabi Abdel-Karim, a spokesman for a faction of the rebel Sudan Liberation Army (SLA) which refused to sign a peace agreement with Sudan's Khartoum-based government in May, said the plane fired a rocket at a house in the village of Hashaaba. "Eight people from the same family were killed," he told Reuters via satellite telephone. "Most of them are children."He gave what he said were the names of the eight people, including 50-year-old Fatmah Abdullah and seven children whose ages range between three and 13 years old. The incident could not be independently verified.
