As at the beginning of April 2012, there were 5,715,096 refugees and internally displaced persons (IDPs) in the eastern Africa region. This represents an overall increase of 291,882 people (5.4 per cent) between 30 September 2011 and end-March 2012. The Democratic Republic of the Congo (DRC) and Somalia continue to host more than one million IDPs each, while Kenya, Ethiopia and Tanzania host more than 250,000 refugees each. Attacks by the Lord’s Resistance Army (LRA) constitute a major trigger for the internal displacements in eastern DRC. OCHA estimates that 73 per cent (340,984) of the 466,637 IDPs in Orientale Province resulted from LRA activities.
