Loved ones of the five people onboard the missing Titanic submersible have asked people to pray for their safe return home.
The submarine-like vessel is trapped beneath the Atlantic Ocean with three British passengers on board, including Pakistani British-based businessman Shahzada Dawood and his 19-year-old son, Sulaiman Dawood.
British billionaire adventurer Hamish Harding is also on the vessel, as is French submersible pilot Paul-Henry Nargeolet, and chief executive and founder of OceanGate Expeditions, Stockton Rush.
