The rescue operation in the Uttarkashi tunnel collapse incident entered the fifth day on November 16.
The father of one of the 40 trapped workers spoke to his son, assuring him that he will be fine.
"My 20-year-old son Vijay Kumar is trapped inside...I spoke to my son a little bit and I gave him courage, assured him that everything would be fine and he would be brought out by tonight...food and water are being provided to them in small quantities," said Dharam Singh, the worker's father.
A heavy drilling machine was airlifted from Delhi by three IAF transport aircraft to replace the "failed" equipment which was being used earlier to create a passage for the workers.
Meanwhile, Indian American Congressman Shri Thanedar has urged the United States Agency for International Development to provide immediate assistance in the ongoing rescue operations
