The manager of a collapsed South African mine says rescuers were forced to suspend a search for three people trapped underground for more than a week.

Lily gold mine manager Mike Begg said rescue teams were evacuated after a second collapse on Saturday. Begg said teams of 40 people have been searching underground since Feb. 5, when the mine in the eastern Mpumalanga province collapsed.

Rescuers are trying to reach mineworkers trapped inside a mobile office container buried under thousands of tons of debris. Begg said there have been no signs of life from inside the container since Tuesday.

Begg said the search would resume once conditions were safe.

The mine, owned by Australia-based Vantage Goldfields, collapsed when an underground pillar caved in, creating a sinkhole that swallowed the container.
