Construction workers freed from China tunnel collapse
Five construction workers have been rescued after being trapped in a collapsed railway tunnel in northwest China for two days.
They had been working in the tunnel in the city of Lanzhou when the collapse occurred at about 2.30pm local time on Wednesday.
That evening a 14cm wide hole was dug to deliver food and water, and later a camera and telephone line.
The men were eventually freed at 10pm on Friday night.
