Indonesia's state oil and gas company Pertamina has confessed to causing a spill that caused a wall of flames to engulf a bulker at Balikpapan.
It said a leak occurred from one of its pipelines being used to transfer crude, the Jakarta Post reported.
The oil was ignited on 31 March, possibly by a discarded fisherman's cigarette, starting a fatal blaze that damaged the 82,000-dwt Ever Judger (built 2014).
