One sailor was killed and another suffered leg injuries yesterday in an accident aboard a cruise ship belonging to Louis Cruise Lines, the company that owned the Sea Diamond which sank off Santorini in April. The accident occurred when a cable being used to moor the vessel in the port of Myconos struck the sailors. The cause of the accident was not immediately clear. The local coast guard has launched an investigation. None of the 480 passengers on board the Orient Queen was injured. The vessel was on a cruise of several Greek islands. Authorities said the sailor who was killed was an Indonesian national, as was his colleague who was injured. Louis Cruise Lines expressed its regret over the incident but said that both sailors had been wearing protective clothing and helmets when the accident took place. The company said that the strong wind could have caused the cable to snap and hit the sailors. Sources told Kathimerini that the wind had been blowing at 6 Beaufort at the time the ship was trying to dock.
