Uttarkashi, November 17: Explaining the delay in the ongoing rescue operation for 40 labourers trapped inside the under-construction tunnel which collapsed in Uttarakhand's Uttarkashi, NHIDCL Director Anshu Manish Khalkho said the delay was due to the fragile nature of the location. Explaining to the reporters, Khalkho said, "Where you feel the fragile nature and vibration needs to be taken care of equilibrium also has to be maintained. So this needs to be done very precisely/ We also have to take care of the morale of people trapped inside and as well as the rescue team outside."

When asked about what time trapped labourers will be able to sustain, Khalkho said, "Without food, a man can survive for six days. Here food and water are provided so from physical health to mental health of the workers is fine. We are communicating with them, and now doctors from the administration have reached out to counsel them." During an earlier update, Khalkho said that rescuers have managed to drill through 24 metres into the rubble inside the Silkyara Tunnel, and are getting closer to 40 labourers who have been trapped inside, following the collapse of the under-construction tunnel for six days now.
