Four people were killed Monday after a tanker exploded at a shipyard in North Sumatra, Indonesia.
The blast occurred Monday evening aboard the MT Palu Sipat while docked at the PT Waruna Nusa Sentana shipyard in Belawan.
Three workers were killed instantly and a fourth later died from severe burns.
The Indonesia-flagged Palu Sipat is owned by the state-owned oil and natural gas company PT Pertamina.
The cause of the accident is under investigation.
