Even as relief and rescue operation continued on war footing, fresh debris falling from the roof of the tunnel are hampering the rescue work.
Rescuers had prepared a platform for the auger drilling machine to insert large-diameter steel pipes into the debris-filled tunnel, that aims to create a passage through which labourers could be brought out safely.
However, visuals from the site showed rescue officials using JCB machines to remove the fresh debris and working to mount the auger machine on the platform again to push the steel pipes into the tunnel.
