Authorities in Indonesia’s eastern province of Papua are delivering food and aid to villages where security forces say an armed rebel group has blocked residents’ movements as police and military surround the area, a police official said on Sunday. Previously on Saturday, the security forces were preparing to storm five villages near a giant copper mine, operated by the American Freeport-McMoRan company. About 1,300 residents were being held hostage by two dozen separatists who authorities said were part of the Free Papua Movement (OPM), which has been fighting a long-running insurgency marked by periodic bouts of violence.
