Death toll of explosion on Brazilian oil ship rises to 5; 4 are missing

An oil workers union says another two bodies were found inside an oil ship that exploded off Brazil's coast, increasing the death toll to five.

Rescue teams are searching for four workers who remain missing.

The Oil Workers Union of the state of Espirito Santo said Thursday on its Facebook page that the bodies were found inside the engine room of the vessel. It is one of many floating oil production, storage and offloading units that Petrobras employs in developing Brazil's massive offshore oil fields.

The ship was leased by Petrobras from Norway-based BW Offshore.
