(CNN) -- Two passengers aboard a cruise ship were killed when 26-foot waves crashed into the vessel Wednesday, officials said. As many as 14 others were injured.
Five windows in public areas were smashed, and two passengers, a German and an Italian, were killed, he said.
Fourteen others were treated for light injuries, Maratheftis said.
The vessel, the Louis Majesty, was sailing under a Maltese flag and traveling from Barcelona, Spain, to Genoa, Italy, the Greek Public Ministry of the Mercantile Marine said.
The ship had 1,350 passengers and 580 crew on board, the ministry said.
After being struck, the cruise ship turned around and was heading back to port in Barcelona.
Buoy data off the French coast indicated that weather was the likely cause of the high waves. Winds were at 45 mph at that buoy.
