At least 28 people were rescued after a boat carrying tourists capsized off Egypt's Red Sea coast, as authorities continued to search for 17 others who are missing after the accident.

The boat, Sea Story, was carrying 45 people, including 31 tourists of varying nationalities and 14 crew, on a multi-day diving trip when it went down near the coastal town of Marsa Alam, according to a separate statement by the governorate.

Egyptian armed forces frigates and aircraft swept the area to try to locate the missing, but by 5:00 p.m. (1500 GMT) the search had been paused for the night, a government source said.

The governorate said a distress call was received at 5:30 a.m. (0330 GMT) and that the boat had departed from Porto Ghalib in Marsa Alam on Sunday, with plans to return to Hurghada Marina on Nov. 29.

Red Sea governor Amr Hanafi did not give information on the nationalities of the tourists, but Polish Foreign Ministry spokesperson Pawel Wronski told state news agency PAP that two people on board may have Polish citizenship.

The Red Sea is a popular diving destination renowned for its coral reefs and marine life and is important for Egypt's vital tourism industry.

Hanafi said that the boat likely sank near the Sataya Reef, without giving further information.

The Egyptian Red Sea Ports Authority said in a statement that it had closed maritime traffic in the area on Sunday at noon when the wind speed reached 34 knots and wave height reached 3-4 meters (10-13 ft).

This is the second boat to sink in the same area this year. In June, a boat sank after it suffered severe damage from strong waves, the Environment Ministry said at the time. No casualties were reported.
