A Carnival cruise ship, Carnival Triumph, is seen in this undated handout picture provided by Carnival Cruise Lines to Reuters on February 10, 2013. Carnival Triumph which was carrying over 4,000 people has lost propulsion, is on emergency back-up power in the Gulf of Mexico and will have to be towed to shore, the cruise lines said in a statement on Sunday. According to a press release, there was a fire in the engine room of the Carnival Triumph Sunday morning as the ship sailed approximately 150 miles off the coast of Mexico’s Yucatan peninsula. The fire was extinguished without injuries but the ship lost propulsion and is now operating on emergency generator power.
