At least 15 people were trapped underground Wednesday when an unlicensed gold mine in western Colombia collapsed, authorities said as rescue workers raced to reach them.

"A mine collapsed, apparently after flooding caused by the holes drilled to extract the mineral. At least 15 people are trapped," said Luis Pineros of emergency response agency UNGRD.
