Noises have been detected from the search area of the missing deep-sea vessel near the wreck site of the Titanic as those on board face a dwindling supply of oxygen.

The submersible, named Titan, lost communication with tour operators on Sunday while about 435 miles south of St John’s, Newfoundland, during a voyage to the shipwreck off the coast of Canada.

Former Royal Navy commander Dr Chris Parry tells TalkTV’s Julia Hartley-Brewer that “people are grasping at straws” after rescuers searching for the Titanic sub heard 'banging sounds'.

“You get a lot of mechanical noise in the ocean. Trying to differentiate it from tapping noises is a fool’s errand.
