A Russian bride-to-be who was doing yoga at an idyllic viewpoint when she was swept out to see by a rogue wave has been found dead.

Tourist Kamilla Beliatskaya, 24, was on a romantic break with her boyfriend when visited the beach alone. She rolled out her pink foam mat before relaxing with stretches at the Lad Koh viewpoint on the island of Koh Samui in southern Thailand, on November 29.

But moments later a powerful wave slammed into the rocks and dragged the young woman - who had taken pre-wedding photos with her partner days earlier - out into the choppy ocean.

Footage from an onlooker shows the moment she was struck followed by her briefly floating in the water. CCTV recovered by police also shows the moment she was dragged away.

However, when rescue teams arrived they could only see her pink yoga mat floating in the surf and the conditions were too dangerous for them to enter the water.

Tragically, her lifeless body was found washed up on the island's busy Chaweng Beach on December 1.

Kamilla's devastated partner Grigorii Anokhin, 47, said: 'I was still praying for a miracle, that my fiance would be found alive. I'm devastated, I'm heartbroken. We were going to get married in a few days.'

Grigorii said that Kamilla had played tennis at their hotel resort before stopping by the reach to relax.

He added: 'I only found out what had happened from social media. I was devastated and immediately went to the area to help look for her.

'I have been with my girlfriend for five years and we were planning to have a wedding in mid-December. We had already taken pre-wedding photos in the hope of living together when we returned to Russia.'

Officers said that rescue teams arrived moments after Kamilla was dragged into the sea. But they could only see her pink yoga mat floating in the surf and the conditions were too dangerous for them to enter the water.

Jet skis, normally rented to tourists on the nearby beach, had also been moved inland due to the choppy sea conditions.

Police eventually dispatched two jet skis to search the stretch of coastline. Rescue teams were also sent out on foot to nearby beaches.

The search was called off at nightfall and resumed on Saturday morning.

Police said they received a report about the body from staff at a nearby hotel in the early hours of Sunday morning.

Officers led tourist police, doctors, and paramedics to the scene whey they discovered Kamilla's corpse around 0.62 miles from where she was pulled into the water.

Her body was discovered lying face up with blood on her face, from where the waves had swept her against the rocks. She was wearing a white long-sleeved top, shorts, and an Apple Watch.

Police Senior Sergeant Major Suporn Hemrangsee said: ‘We took her body for an autopsy at Koh Samui Hospital. 'We also informed her parents in Russia to retrieve her body for religious ceremonies.

'The tourist was caught off guard by the large wave, which was sudden and unexpected.

'Life guards could not immediately enter the water as the conditions were too dangerous.

''The obstacle to entering the sea was the high waves. They were two or three meters high and the conditions were very rough, which may have caused the tourist to lose strength.

'There are warning flags on the beaches during this time of the year. It is not safe for tourists to enter the water. They should not get too close to the sea.'

Thailand's unpredictable seas are at their most dangerous in October, November and December when the monsoon season is reaching its peak.

Dozens of holiday makers are killed every year when they are dragged away by the powerful currents.
