Rescue workers at a US-owned mine in eastern Indonesia freed four out of 37 miners who were believed trapped underground when a tunnel collapsed.
The accident occurred when 40 workers were gathered in a classroom inside a training tunnel about 500m (1,640ft) from the entrance of the Big Gossan Mine in Papua province. The mine is owned by Freeport-McMoRan Copper & Gold Inc.
Three workers escaped unharmed, while four others were later freed by rescuers. Of those, one was taken to a hospital in stable condition.
