The families and friends of the five people on board the submarine-like vessel trapped beneath the Atlantic Ocean made a desperate plea for people to pray for their safe return.
Pakistani British-based businessman Shahzada Dawood and his 19-year-old son, Sulaiman Dawood, were confirmed to be on the submersible.
Their identities followed British billionaire adventurer Hamish Harding who is also in the vessel, along with French submersible pilot Paul-Henry Nargeolet, and chief executive and founder of OceanGate Expeditions, Stockton Rush.
