Rescue begins of ailing U.S. researcher stuck 1,000 metres inside a Turkish cave, Turkish officials say

Man freed from cave says he'll continue to explore A U.S. researcher who was trapped 1,000 metres below ground says the ordeal hasn't deterred his interest in cave exploring.

TASELI PLATEAU, Turkiye — Rescue teams began the arduous process Saturday of extricating an American researcher who became seriously ill while he was 1,000 metres (3,000 feet) below the entrance of a cave in Turkiye, officials said.

It could take days to bring Mark Dickey to the surface since rescuers anticipate he will have to stop and rest frequently at camps set up along the way as they pull his stretcher through the narrow passages.

"This afternoon, the operation to move him from his camp at 1,040 metres to the camp at 700 metres began," Turkiye's Disaster and Emergency Management Directorate, AFAD, told The Associated Press.

The 40-year-old experienced caver began vomiting on Sept. 2 because of stomach bleeding while on an expedition with a handful of others in the Morca cave in southern Turkiye's Taurus Mountains.

Rescuers from across Europe rushed to the cave to help Dickey and to extract him, including one Hungarian doctor who treated him inside the cave on Sept. 3. Doctors gave Dickey IV fluids and 4 litres (1 gallon) of blood inside the cave, officials said. Teams comprised of a doctor and three or four others take turns staying with the American at all times.

There are 190 personnel from eight countries assisting in the rescue effort, including doctors, paramedics and experienced cavers, Mersin Gov. Ali Hamza Pehlivan told media on Saturday. He said 153 of them were search and rescue experts.

"We have received information that his condition is getting better, thanks to medical intervention. He has been in stable condition as of yesterday," he said.

Speaking with the AP before rescue operations began, Recep Salci, head of AFAD's search and rescue department, said the rescue will depend on Dickey's condition.

"If he feels well, we will assist him, and he will come out (of the cave) fast. But if his condition worsens, we will have to bring him up on a stretcher." He said bringing Dickey up in a stretcher could take up to 10 days.

Yusuf Ogrenecek of the Speleological Federation of Turkiye says that one of the most difficult tasks of cave rescue operations is widening the narrow cave passages to allow stretcher lines to pass through at low depths.

"Stretcher lines are labour intensive and require experienced cave rescuers working long hours," Ogrenecek said, adding that other difficult factors range from navigating through mud and water at low temperatures to the psychological toll of staying inside a cave for long periods of time.

In Rome, Federico Catania, the spokesman for Italy's National Alpine and Speleological Rescue, described the cave as one of the deepest in the world.

"The cave is made up of many vertical shafts, so many sections that are extremely vertical with few horizontal sections where (the) rescuers are setting up temporary camps," he said.

Turkish authorities made a video message available that showed Dickey standing and moving around on Thursday. While alert and talking, he said he was not "healed on the inside" and needed a lot of help to get out of the cave. He thanked the caving community and the Turkish government for their efforts to rescue him.
