JAKARTA, Indonesia—An explosive eruption Friday of Mount Dukono on the remote Indonesian island Halmahera killed three hikers and injured five who were climbing in a restricted area around the active volcano, authorities said.
About 20 climbers had set out Thursday to ascend the nearly 1,355-meter (4,445-foot) volcano in defiance of safety restrictions, said North Halmahera police chief Erlichson Pasaribu.
