A team of nearly 150 rescuers are about to start the rescue of an American man who became seriously unwell while exploring the Morca Valley in Turkey alongside a research team.
Mark Dickey, 40, is an instructor with the US National Cave Rescue Commission. He was co-leading an expedition to find and map a new passage in the Turkish cave that takes an experienced caver 15 hours to traverse when he started to suffer from gastrointestinal bleeding.
