At least five people were killed and seven others badly injured Friday in an accident at a gold mine in southwestern Colombia, the Nariño provincial government said.

The accident occurred before noon at the La Profundidad site, which lies in a remote patch of jungle that can only be reached by boat or aircraft.

Initial reports spoke of 10 dead and dozens hurt and missing.

Colombia's air force transported the injured to hospitals in Pasto, the provincial capital.

The cause of the accident remains unknown. EFE
