Four helicopters were sent Tuesday to retrieve bodies from the wreckage of a small passenger plane that crashed last week on Sulawesi island, police said.
The DHC-6 Twin Otter operated by domestic airline Aviastar was carrying 10 people Friday when it disappeared shortly after takeoff from the town of Masamba.
Searchers located the plane Monday afternoon on rugged Mount Latimojong following information from residents.
“Based on information from the location, there are no survivors,” provincial police spokesman Frans Barung Mangera said.
The cause of the accident was still unclear, officials said.
Transport Minister Ignasius Jonan said authorities were investigating a report that the pilot did not fly the determined route, instead taking a shortcut in violation of regulations.
Indonesia, which has a reputation for poor aviation safety, has experienced four deadly air accidents since December.
In August, an ATR 42-300 plane operated by Trigana Air Service crashed into a mountain in Papua province, killing 54 people on board.
