Two seafarers have been killed after a supramax bulker reportedly suffered an explosion while sailing off Cape Cod in the Atlantic.

The incident, which happened aboard the 56,600-dwt Tamar (built 2010), has also seen three other seafarers suffered massive burns.

The master of the Splosna Plovba-owned ship said the vessel suffered an explosion in its forward storeroom, reports the US Coast Guard (USCG).
