Falling rock kills US tourist


San Juan – A Californian woman died after being hit by a falling rock on Saturday while visiting a vast cave system in north-western Puerto Rico, authorities said.

Socorro Elaine Smith, 45, of Los Angeles, was struck while waiting with her husband and son to board a trolley that runs through the Camuy caves, authorities said.

No one else was injured, but the Rio Camuy Cave Park was evacuated, Puerto Rican police spokesperson Marilyn Calo said.

The caves are one of the biggest cave systems in the world and a major tourist attraction on the US territory.
