A medical charity has accused the Angolan Government of criminal and chronic negligence of its own people, which it said had left nearly half a million Angolans facing starvation. Medecins sans Frontieres (MSF) said at a news conference in Luanda that malnutrition in Angola was the worst its staff had seen since Sudan's devastating famine several years ago. It accused the Angolan Government, and the United Nations, of responding too slowly to the crisis, in a way that it said was totally unacceptable. A ceasefire in the civil war agreed in April has given aid workers access to new areas - revealing the extent of the food shortages. A UN delegation is currently in Angola to assess the plight of people displaced by the war and check on progress towards demobilising the former rebels.
