Egyptian authorities say 16 people are missing, including foreigners, and 28 have been rescued after a tourist boat sank in the Red Sea.

Two of those missing are British, the BBC understands. Finland has confirmed one of their nationals is unaccounted for, while authorities say four Egyptians are also missing.

The boat with 44 people on board – sent a distress signal at 05:30 (03:30 GMT), according to the governor of Red Sea province.

Authorities have not indicated the possible cause of the incident, but added there were no technical faults onboard. Weather forecasters however warned against marine activities for Sunday and Monday.

The Sea Story left port near Marsa Alam on Sunday for a five-day diving trip, according to officials.

Red Sea Governor Maj-Gen Amr Hanafi said the survivors were found in the Wadi el-Gemal area, south of Marsa Alam, and that they were receiving the necessary medical care.

Hanafi added that the Egyptian Navy warship El Fateh and military aircraft were intensifying their efforts to locate the missing.

“Intensive search operations are under way in co-ordination with the navy and the armed forces,” he said.

On Saturday, the Egyptian Meteorological Authority forecast turbulence on the Mediterranean and Red Seas due to the weather.

Wind speeds were between 37-43 mph (60-70 km/h), and wave heights were three to four metres (10-13ft) high, they said.

According to the local council in Marsa Alam, the crew of the Sea Story are all Egyptians and the tourists on board included five Spanish, four British, four Germans and two US nationals.

It is unclear who is among the rescued and who is still missing, but the Red Sea governorate’s latest report said four Egyptians are missing.

The Finnish foreign ministry confirmed to AFP news agency that one of its nationals is also among the missing.

A British Foreign Office spokesperson said they were in contact with the authorities, and were providing “support to a number of British nationals and their families following an incident in Egypt”.

The Chinese embassy in Egypt confirmed two of its nationals were “in good health” after being rescued, according to their state media, as reported by AFP.

Meanwhile, Polish foreign ministry spokesman Pawel Wronski, told state-run Polish news agency PAP that authorities had information that two Polish citizens may have been aboard the boat.

Earlier reports from Egyptian authorities said there had been 45 people on the Sea Story when it sank – 14 crew and 31 tourists.

Marsa Alam is a popular destination for tourists on Egypt’s southern Red Sea coast and is surrounded by diving spots, including renowned coral reefs.

A staff member of a diving resort close to the rescue operation told AFP that a rescued crew member said they were “hit by a wave in the middle of the night, throwing the vessel on its side”.

There was no immediate comment from Sea Story’s Egypt-based owner and operator, Dive Pro Liveaboard.

But its website says the vessel was built in 2022 and is 44m (144ft) long. It has four decks and 18 cabins that can accommodate up to 36 passengers.

Last year, three Britons died off the coast of Marsa Alam after their dive boat caught fire.
