CAIRO — A recreational submarine taking 45 tourists on an underwater cruise of coral reefs in the Red Sea sank off the Egyptian resort town of Hurghada on Thursday, leaving six Russians dead, the provincial governor said. The remaining tourists, more than two dozen of whom were injured, were rescued, he said.

The cause of the sinking was not immediately known. The Russian consulate said it took place about half miles offshore.

The submarine was carrying 45 tourists and five Egyptian crewmembers when it sank, Red Sea governor Maj. Gen. Amr Hanafi, said in a statementt.

He said all six dead were Russians, and that 29 of the 39 tourists rescued were injured and taken to hospitals. No one was still missing from the vessel, he said.

Hurghada is a major destination for divers, snorkelers and other tourists.

The submarine, named “Sindbad,” runs tours lasting about 40 minutes underwater, cruising at about 20-25 65-80 feet underwater with panoramic windows on the bottom to give views of the marine life, it was reported.
