BOGOTA - Colombian rescuers used dogs on Sunday to locate bodies buried in a landslide that swamped an open pit gold mine killing at least 22 workers, a Red Cross spokesman said.

The search for 15 missing workers at the small, privately owned Suarez Gold Mine in the southwestern province of Cauca was hindered by the same heavy rains that caused the landslide on Saturday.

"It is still raining but less intensely. So we are able to continue today using search dogs and land-moving equipment," Colombian Red Cross spokesman Carlos Marquez said.

About 24 miners were treated for injuries on Saturday, Marquez said.
