Emergency services in Spain's northeastern region of Catalonia say they have deployed 40 rescue experts to extricate an injured caver from deep underground.

A phone call Saturday alerted firefighters to the emergency inside the Cuberes cave in the municipality of Conca de Dalt. Preliminary information from the call indicated a caver had fallen six meters (20 feet) in an area about a three-hour hike from the cave entrance.

A team including 19 rescue specialists, a doctor and nurse, seven underground climbers from the Catalan Speleology Federation and 12 police have been flown to the cave.

Another emergency medical group arrived Sunday to wait for the rescuers to surface with the injured caver and the three other cave climbers who had been with him.
