Clashes between the MILF and Armed Forces of the Philippines (“AFP”) continued and caused the number of IDPs to fluctuate. Two years after hostilities ended between the AFP and MILF, the Office of the Presidential Adviser on the Peace Process (OPAPP) reported in July 2011 that 4,538 displaced families -- a substantial reduction from previous years--were living in camps and relocation sites in southern Mindanao, with a majority in Maguindanao Province. The NGO Internal Displacement Monitoring Center (IDMC) reported a February figure of approximately 15,000 IDPs remaining in camps. Other IDPs were living in informal settlements or with host communities in both rural and urban areas, but they were not included in official government data.
