'Shaking with cold': Tourists from Egypt boat sinking brought ashore

Egypt released video footage on Wednesday of the latest tourists rescued from a boat that capsized off the country's Red Sea coast, where at least four people lost their lives.

Seven people remain missing more than two days after the "Sea Story" was struck by a wave and overturned in the middle of the night.

The vessel had set off Sunday from Port Ghalib, near Marsa Alam in the southeast, on a multi-day diving trip with 31 tourists -- mostly Europeans, along with Chinese and US nationals -- and a 13-member crew.

Thirty-three were rescued, including tourists seen in the video stepping off a speedboat, draped in blankets, at a marina near Marsa Alam.

"We were shaking with cold," one unidentified man said in the footage.

The tourists who appeared in the video had spent at least 24 hours inside a cabin of the overturned vessel before rescuers found them Tuesday morning, according to a government source close to the rescue operations.

A military-led team on Tuesday rescued two Belgians, one Swiss national, one Finnish tourist and one Egyptian, authorities said.

Two survivors -- one identified by authorities on camera as an Egyptian -- were rolled out on stretchers, one of them conscious and speaking.

Dozens of dive boats crisscross between Red Sea coral reefs and islands off Egypt's eastern coast every day, where safety regulations are robust but unevenly enforced.
