ISTANBUL: Turkish rescuers raced on Thursday to save an American who developed internal bleeding while exploring a cave more than 1,000 metres (3,300 feet) below ground level.

Turkiye’s Caving Federation said 150 rescuers were trying to reach Mark Dickey, 40, who developed gastrointestinal bleeding while deep inside the Morca Cave, near Turkiye’s Mediterranean coast.

“The operation is logistically and technically one of the largest cave rescues in the world,” the federation said in a statement.

Dickey fell ill at a depth of 1,120 metres while accompanied by an international team of explorers.

He was placed under observation at a base camp located 1,040 metres underground, where he was given infusion of blood delivered by rescuers and medics, the federation said.

The federation launched a rescue operation with the help of Turkiye’s emergency response service on Tuesday. The DHA news agency said Dickey first fell ill on Sunday.

“Mark’s condition is becoming stable,” the caving federation said. “His bleeding has stopped and he can walk with help, but it is not possible for him to get out without a stretcher.”
