Rescue efforts are under way in a remote village in northern Ethiopia where more than 20 artisanal miners are trapped inside a cave. It’s been three days since a narrow cave collapsed on the miners in the Delanta district. Local officials are uncertain about the exact number of the trapped miners, who were looking for precious opal gemstones. The officials said that in a previous incident, a miner was found alive after he was buried inside the cave for seven days. He is among hundreds of of locals trying desperately to free more than 20 miners who became trapped in a cave three days ago while looking for opals.
