More than 6,400 people have been killed since 2004 in a simmering conflict pitting shadowy Malay-Muslim rebels against security forces from Thailand, which annexed the region more than a century ago. The majority of victims were Buddhist and Muslim civilians targeted for their perceived support for the Thai state.
