Uttarkashi tunnel rescue delayed as drill machine hits hurdle
Rescue operations at the Silkyara tunnel were delayed for hours on November 23 as the drilling machine ran into an iron lattice girder, a structural element of the tunnel which had been buried in the debris and had to be removed manually. The machine only managed to bore through two more metres of debris by 6 p.m. on November 23, frustrating efforts to reach the 41 workers trapped by the collapse of the tunnel since November 12.
