Rescue Efforts At Uttarakhand Tunnel Go Slow, Senior Official Explains Why

"Different machines are being used to stabilise the loose soil but inch by inch the team is progressing," said NDRF Inspector General Narendra Bundela

Efforts are on to rescue the 40 workers inside an under-construction tunnel in Uttarakhand that collapsed early on Sunday. Officials say the workers -- who have been trapped in a buffer zone -- are unharmed and are being supplied with food and water by a long pipe. But 35 hours on, the rescue teams have made little headway in cutting down the rocks that fell over a 200-meter area, trapping the workers inside the tunnel.

Speaking to NDTV about the progress of the work, NDRF Inspector General Narendra Bundela said: "Regarding the amount of time to be taken, I'll not be able to comment just now… The work is progressing and definitely the team will be able to reach there."

"Different machines are being used to stabilise the loose soil but inch by inch the team is progressing," he added.
