Rescuers in Italy working to free cave explorer trapped underground

MILAN (AP) — A major rescue operation is underway in a cave northeast of the Italian city of Bergamo to free a woman who was injured in a fall and became trapped while exploring with eight other people. Ottavia Piana, 32,  remained blocked deep inside the Bueno Fonteno cave, where the temperatures were ranging from 7 degrees Celsius to 8 degrees Celsius (44-46 degrees Fahrenheit) in high humidity. Piana, considered an expert cave explorer, was injured after falling some 5 meters (16 feet) Saturday evening during an expedition to map a kilometer (half a mile) of an uncharted branch of the cave, but rescuers said she is alert and responsive.
