A TEACHER died along with her teenage daughter and one of her twin sons in the Red Sea submarine disaster.

Lyudmila Gordeeva, 35, was killed alongside her daughter Sofia, 13, and one of the her three-year-old twins.

The other twin and the children’s dad Alexander survived the tragedy off the coast of Hurghada in Egypt, reports Russian outlet The Voice Mag.

The two surviving members of the family, from from Vyborg, in Russia, are both in hospital.

Lyudmila and her two children are among six Russian tourists who died yesterday with the Sindbad tourist submarine sank.

And it is reported many of the bodies of the those killed are still trapped inside the bathyscaphe.

It sank as water poured into it as it was loading passengers with its hatches open.

Lyudmila had moved to Russia from Berdychiv, Zhytomyr region, in Ukraine, around  a decade ago.

She was a music teacher and accompanist at the Vyborg School of Arts, and was in the Red Sea resort on a family holiday.

The tragedy happened when the submarine sank as passengers were boarding. 

Seven Russian tourists – five of them children – remain in hospital after the latest tourist tragedy to hit the Red Sea.

Lyudmila’s family is the second known to have been devastated by the Egyptian tourism horror. 

The Russian authorities today confirmed that anaesthetist Dr Ravil Valiullin, 40, a father of two, was killed in the tragedy. 

He was on the Hurghada vessel with his wife, Dr. Kristina Valiullina, 39, while their daughters, aged ten and fifteen, were aboard the bathyscaphe and survived.

His wife was initially reported dead due to an error on victims by the Egyptian authorities. 

In fact, she survived and is now in hospital with their daughters. 

Ravel was reportedly an avid Liverpool FC supporter. 

Like his wife, he worked  at the Urussu Central Regional Hospital in the Russian region Tatarstan. 

Russian Channel 5 reported, “The primary theory regarding the tragedy is believed to be a crew error on the submarine, though concerns about the bathyscaphe’s technical condition and the organization of tourist dives are also under consideration.”

“Following the incident, the Egyptian authorities imposed a temporary ban on all excursions using submarines.”

It comes after horror footage showed the moment the sub sank at it began its dive into the Red sea.

Tourists climbing on board can be heard screaming with panic in the chaos.

Water quickly starts to rise around the holidaymakers’ feet as the craft begins to dive.

The woman notices the rising water and remarks: “That’s it the dive has begun, we are already descending slowly.”

Panicked children then begin to scream as the submarine descends fast and within seconds the holidaymakers are left swimming for their lives.

The phone is plunged into the water for several seconds before it cuts out.

The hatch of the craft can still be seen open in the clip, suggesting that seawater would have rushed into the vessel.

Tourist Regina told Russian media that she was on top of the craft with her two children, aged nine and ten, when the disaster happened.

She said: “We were queuing at the boarding, when the submarine began to sink into the water.

“The Egyptian who was responsible for loading shouted ‘Stop, stop!’.

But naturally no one inside heard him.

“He shouted to us ‘Faster, faster, go to the pontoon’ from which people were boarding.”

The woman then had to swim for her life away from the sub as she feared she would be sucked beneath the waves before managing to reach the pontoon.

She said: “There was not a single life preserver, no lifebuoys, no vests, nothing at all on the pontoon itself.”

Survivors were then rescued by boats which quickly picked them up and delivered them to shore, with 39 rescued.

The crew of the sub are now being questioned by Egyptian officials.

Red Sea Governor Amr Hanafy confirmed yesterday the submarine had a valid licence and the crew had all obtained the correct certificates.
