CAIRO, Egypt — An Egyptian ferry carrying about 1,300 people sank in the Red Sea overnight during bad weather, and rescue ships and helicopters pulled dozens of bodies from the water Friday, an official said. About 100 survivors in lifeboats were rescued.

The 35-year-old ship, Al-Salaam Boccaccio 98, went down 40 miles off the Egyptian port of Hurghada, the head of the Egyptian Maritime Authority, Mahfouz Taha Marzouk, told The Associated Press.

Britain’s top naval officer said he diverted the warship HMS Bulwark to the north Red Sea site, and it will arrive within two days. But the U.S. 5th Fleet in Bahrain said Egyptian authorities turned down an American offer to divert a U.S. P3-Orion naval patrol aircraft to the area.

Four Egyptian rescue ships reached the scene today, about 10 hours after the ship likely went down.

There were high winds and a sandstorm overnight on Saudi Arabia’s west coast, where the ship departed from. The ship sailed from the Saudi port of Dubah at 7 p.m. Thursday night and was scheduled to arrive at Egypt’s port of Safaga — 120 miles away — eight hours later.

The passengers included about 1,200 Egyptians, 99 Saudis, three Syrians, two Sudanese and a Canadian.
