CAIRO: A senior United Nations official on Friday called for more international attention to “the forgotten crisis” in Sudan, where more than a year and a half of war pushed the African country to the brink of famine. The appeal by Ted Chaiban, deputy head of the UN children’s agency UNICEF, came as the notorious paramilitary Rapid Support Forces rampaged through villages and towns in east-central Gezira province, looting and vandalizing public and private properties, according to a doctors’ union and a youth group. Dozens of people were reported killed.
