Rescuers are making a last-ditch effort to locate a submersible that went missing on its way to the Titanic wreckage site. Experts fear the oxygen on board may have already run out.
The US Coast Guard said that rescuers uncovered a "debris field" within the search area where teams are searching for the missing Titan submersible that was traveling to the wreck of the Titanic.
"A debris field was discovered within the search area by an ROV near the Titanic. Experts within the unified command are evaluating the information," the US Coast Guard wrote on Twitter.
The Coast Guard is expected to provide more details later on Thursday, with a press conference scheduled for 3:00 p.m. in the US city of Boston (1900 UTC).
The search and rescue operation was in a critical stage on Thursday, with experts concerned that the five people on board may have run out of oxygen.
Rescue organizers rushed more ships and vessels to the site of the disappearance, hoping to locate the tiny vessel after detecting underwater sounds for a second straight day.
