Relief efforts blocked in northern Katanga as fighting continuesNAIROBI, 6 Dec 2005 (IRIN) - The French charity, Medecins Sans Frontieres (MSF) says that the army in northern Katanga Province of the Democratic Republic of Congo (DRC) has blocked relief workers from entering the area since beginning a military campaign against local militias there in mid-November. MSF reported on Friday that some 3,000 internally displaced persons fled fighting in their camp at Mazwombe in Mitwaba Territory. Sailly said the fighting was between the army and one of the Mayi-Mayi militia groups in the area. Public information officials at army headquarters in Kinshasa said they could not comment on operations in northern Katanga or on the army's policy on giving humanitarian workers access to the area. Sailly said she did not know if the official policy was to block relief workers from entering the area.
