Suspected bomb near Papua airport

A suspected bomb has gone off near an international airport in Timika, in Indonesia's easternmost province of Papua, police say.

It was not immediately clear if anyone has been killed or injured in the blast, which reportedly could be heard up to 5km (three miles) away.

The blast occurred on Sunday night near Moses Kilangin International Airport.

On Thursday, unidentified militants set off two small bombs on a road to a nearby gold and copper concession.

The concession is run by PT Freeport Indonesia, a subsidiary of US mining giant Freeport McMoRan.

The same company runs the airport.
