Fresh air found in search for trapped Nepal hydro-plant workers
In short:
Australian tunnelling expert Arnold Dix says Nepali authorities have found fresh air for the first time in the tunnels filled with mud and debris in last month's floods.
A suspected 900 people have been trapped in the tunnels of hydropower projects in Nepal since the August 26 floods buried the tunnels' entrances and cut off those inside.
What's next?
Nepal's Prime Minister Balendra Shah has vowed there would be no let-up in the rescue operations.
