A debris field has been discovered within the search area by a remotely operated underwater vehicle near the Titanic, the US Coast Guard has said.
The US Coast Guard had predicted that the air supply in the vessel would run out at 12.08pm UK time on Thursday.
It disappeared on Sunday in the Atlantic Ocean, some 435 miles south of Newfoundland, Canada, during an expedition dive to see the wreck of the Titanic.
Ships, planes and underwater craft from multiple countries were deployed to the area with rescuers searching a remote part of the Atlantic Ocean more than twice the size of the US state of Connecticut in waters as deep as 4,020m (13,200ft).

The vessel – operated by the US-based firm OceanGate – had five men on board: British billionaire Hamish Harding, British businessman Shahzada Dawood, his son Suleman Dawood, OceanGate’s US-based chief executive and founder Stockton Rush and French submersible pilot Paul-Henri Nargeolet.
