Uttarkashi tunnel collapse: Rescue operation to take 24 hours

Rescue teams are working on evacuating 40 laborers trapped inside an under-construction tunnel in Uttarakhand's Uttarkashi district as rescue efforts entered the third day on Tuesday. The state government has constituted a six-person expert panel to examine the situation as officials said the rescue operation might take 24 hours or more. Officials are planning to horizontally drill a hole in the heap of debris and push pipes with 900mm diameter for the trapped workers to squeeze through and come out.
