(Reuters) -A deep-sea submersible carrying five people on a voyage to the century-old wreck of the Titanic was found in pieces from a "catastrophic implosion" that killed everyone aboard, the U.S. Coast Guard said on Thursday, ending a multinational five-day search for the vessel.

A robotic diving vehicle deployed from a Canadian ship discovered a debris field from the submersible Titan on Thursday morning on the seabed some 1,600 feet (488 meters) from the bow of the Titanic, 2 1/2 miles (4 km) beneath the surface, in a remote corner of the North Atlantic, U.S. Coast Guard Rear Admiral John Mauger told reporters.
