Angry residents of the island of Papua burned cars and shops on Thursday after an independence activist was shot and killed, the police and human rights activists said. A low-level insurgency for independence has simmered on Papua, Indonesia’s easternmost island, for decades. The activist, Mako Tabuni, deputy of a group pushing for a referendum on Papuan self-determination, was shot dead while resisting arrest, said a human rights activist, Markus Haluk. Mr. Tabuni had been campaigning for an investigation into a recent spate of shootings. Papua is the western half of an island that includes Papua New Guinea. Papua’s gold, gas and copper make it one of the richest areas in Indonesia and an attractive site for investment.
