Rescuers work to free injured cave explorer  trapped more than 130 feet underground in Italy

 MILAN, July 21:  A rescue operation was underway Monday to free a cave explorer who was injured by falling rocks some 40 metres below the surface in Italy’s Piedmont region while on an outing with a group of friends, according to the country’s mountain rescue corps.
  Medical teams reached the injured man after the accident on Sunday and were treating him inside a heated tent for a head injury that prevents him from exiting the cave on his own.
Rescuers used explosive charges to widen the cave at three key junctures so the injured man could be carried to the surface. He remained in good condition.
