An explosion hit a Bahamas-flagged ship in the Gulf of Oman off the coast of Muscat, maritime authorities said on Friday. Maritime security company Dryad Global said the vehicle carrier <em>MV Helios Ray</em>, was en route to Singapore from Dammam in Saudi Arabia. All crew members were said to be safe. The ship is<em> </em>owned by Helios Ray Ltd, an Israeli company registered in the Isle of Man. The UK Maritime Trade Operations said the <em>MV Helios Ray</em> was heading to the nearest port, with shipping data suggesting that is Dubai. It is unclear what caused the explosion. "Vessels transiting the area are advised to exercise caution," the agency said. The US Navy said it was aware of the incident and was monitoring the situation.
