(Bloomberg) -- The Portuguese Navy said it’s monitoring a tanker with a fire on board off the Atlantic coast in the north of the country in case there’s any pollution.

The Malta-flagged Greta K tanker was headed to the port of Leixoes in northern Portugal, the Navy said in a statement on its website. It’s carrying diesel and jet fuel, and has no crude oil.

The fire continues to be active and seven of the ship’s 19 crew members remain on board. The tanker is being towed to an area far from the coast.
