Indonesian police officials said on Sunday that three dead bodies were recovered from the water near to a small tanker that suffered an explosion at the Barokah Perkasa yard on the Mahakam River in Samarinda, Indonesia, last Thursday.

They are still trying to determine whether the deceased were victims of the blast or an unrelated drowning.

TradeWinds reported on Friday that footage apparently filmed on a phone by a yard worker showed black smoke billowing from a small tanker before a massive explosion rocked the vessel, resulting in a plume of fire shooting skywards.
