Six Russian tourists died after sinking in the Red Sea near the Egyptian city of Hurghada.
Officials said the other 39 people were rescued after the ship – Sinbad sinks at about 10:00 local time (08:00 GMT). It is said that nine people were injured in critical condition 4 people.
Russia’s TASS News Agency reported that two of them were children.
The authorities are still investigating and it is not known why the incident is caused.
This is the second incident involving a Red Sea tourist boat in recent months. In November, a ship tilted on a ship near Marsa Allam left 11 missing people and presumably dead.
Sinbad has been operating in tourist submarines for many years.
Sindbad, a company that runs the trip, said its ships take passengers to explore coral reefs near the Helgada coastline.
Red Sea Governor Amr Hanafy said the 45 passengers from Sindbad were from Russia, India, Norway and Sweden. Five Egyptian crew members were on board as well.
Mr Hanafi said the six dead were all Russians, but all details of the victims have not been released.
Authorities said there were two married doctors, including the dead, whose daughters remained in the hospital.
An investigation into the incident is underway, but the association of travel agencies cited by Russian tourism operators in the telegram hit the reef, which then put pressure on the depth of 20 meters (65 feet).
Hurghada City is located in the southeast of Cairo, a tourist destination known for its beaches and coral reefs.
Sindbad’s website says its travel allows passengers to travel 25 meters (82 feet) underwater.
Dr. James Aldridge from Bristol made the same trip on the submarine in February 2025. He told the BBC: “The submarine is well maintained, as shown in the promotional photos.
“Fresh paint, modern equipment, and professional and professional English-speaking staff (including two divers accompany you).
He explained that the passengers were given safety briefings recorded in multiple languages and said that life jackets were not issued.
He added: “We visited the reef for 40 minutes. In the first 20 cases where I was facing the reef, the submarine never wandered ‘too close’ and I never felt unsafe. For the return trip, I faced the ocean.”
