Consular support is being provided to “a number of British nationals and their families” after a tourist yacht sank in the Red Sea off Egypt, the Foreign Office said.
There are reports that four Britons who were on board the vessel south of the coastal town of Marsa Alam are missing.
Amr Hanafy, governor of the Red Sea region, said the yacht was carrying 31 tourists and 14 crew.
Twenty-eight people were saved by rescuers.
A distress call was made from the yacht shortly before dawn on Monday.
The vessel had left Marsa Alam for a five-day sailing.
