A row has broken out between the army and residents of Uganda's biggest Internally Displaced Persons (IDPs) settlement, Pabbo camp, in the northern Gulu District, with the army claiming that the camp harbours rebel collaborators and the IDPs accusing the army of starting a fire which destroyed much of the camp during an operation to arrest suspects. Pabbo houses over 62,000 people fleeing Lord's Resistance Army (LRA) operations in northern Uganda. They are part of at least 1.2 million Ugandans who have been forced to take refuge in camps.
