Thousands of Angolan refugees returning home from Zambia face food shortages and get only half rations, a United Nations official said Wednesday. The World Food Programme, which has been feeding refugees in camps and handing out supplies to those returning home, said rations were small especially on the Angolan side, WFP spokesman Mike Huggins told AFP. "Resources for this exercise are extremely tight, especially on the Angolan side where rations have had to be reduced by up to 50 percent," said Huggins.
