The US Coast Guard says presumed human remains have been found within the wreckage of the Titan submersible.
Pieces from the sub, which imploded on a deep dive to the Titanic, were unloaded in St John’s, Canada, on Wednesday.
Officials say the sub’s landing frame and a rear cover were found among the debris.
The coast guard in a statement said US medical professionals will conduct a formal analysis of presumed remains.
The agency is in the early stages of an investigation into the causes of the disaster.
All five people on board the vessel died on June 18, after it imploded about 90 minutes into a dive to view the famous 1912 shipwreck, which sits at a depth of 3,800m in the north Atlantic.
