Indonesian rescuers have upped their efforts to save eight miners trapped in a pit at an illegal mining area since Tuesday.

A joint search and rescue team has brought in six larger submersible water pumps to suck water from the hole and is trying to close off openings where water is seeping in from the groundwater basin.
