One mid-February morning in the central highlands of the Indonesian province of Papua, the army said Prada Ginanjar Arianda, a 22-year-old member of the 400 Banteng Raiders commando battalion, was shot in the stomach by separatist fighters and died.

About 24 hours later, after a sweep by security forces through nearby hamlets that sent hundreds of residents fleeing to the safety of two churches, distraught family members were at a health clinic collecting the bodies of three brothers, Janius, Soni and Yustinus Bagau.

Ever since Papua was incorporated into Indonesia after a United Nations-supervised vote by only about 1,025 people in 1969, Indonesia has tried to quell a rebellion among its distinct Melanesian indigenous population of about 2.5 million who are seeking independence. Papua, rich in resources, has among the worst poverty rates in Indonesia despite $7.4 billion of funding by the central government over the past 20 years.
