Three British tourists are missing after a fire aboard a boat during a cruise in the Egyptian Red Sea.
Twenty-four other people, including 12 Britons, were rescued from the boat, called Hurricane, which was off Marsa Alam, authorities said.
They added that initial reports suggested the fire was the result of an electrical fault.
The boat had been on a diving cruise and left Port Ghalib on June 6 and was due to return on Sunday.
Local authorities said 15 British passengers were on board along with 10 crew members and two guides.
The Red Sea governorate said initial examinations revealed an electrical short in the engine room, while the prosecution opened an investigation.
Everyone who had been rescued was fine.
The Red Sea is a popular resort for diving trips.
“This is really bad news for the tourism industry,” said BBC News correspondent Sally Nabil Nabil. “They depend on tourism, especially British tourism.”
The Foreign Office said it supported the British nationals involved.
A spokesperson said: “We are in contact with local authorities following an incident on board a dive boat near Marsa Alam, and are supporting the UK nationals involved.”
