Deepak kumar (23), a resident of Bihar's Muzzaffarpur is one of the workers trapped inside the tunnel.

Deepak's maternal uncle Abhay Kumar Singh told ANI that he had spoken to Deepak through the pipeline at 6 pm on Friday evening.

"My nephew Deepak Kumar is trapped here. Today we have been here for 4 days and every day we are assured that they will be taken out today. The machine has been closed since yesterday. When I talked to him yesterday evening, he said that everything is fine. There is some problem of urination though inside the tunnel," Abhay Kumar Singh said.

He further said that everyone at Deepak's home is worried and has stopped eating food.

"Calls are coming from home every day; what answers should I give to them? Everyone at home is worried. Everyone has stopped eating and drinking for a week. I have given assurance at home but nothing is happening here," he added.

The ongoing drilling work to reach the 40 trapped workers inside the Silkyara tunnel was halted on Saturday after the rescuers bored 25 metres into the rubble, a top official said.

The workers have been trapped for six days, counting Saturday, after a portion of the under-construction Silkyara tunnel caved in on November 12.

Speaking to ANI over the telephone, Anshu Manish Khulko, director of the tunnel-making company, NHIDCL, said the drilling work to reach the trapped workers is suspended for now.

Asked if the drilling work was stopped due to a snag in the machine being used in the rescue operation, Khulko added, "There was no fault in the machine."He also said the managing director of NHIDCL is expected to reach the incident site on Saturday and will share further details after taking stock of the ongoing rescue work.

On Friday, the Auger machine engaged in the drilling work stopped functioning after it hit a rock face. However, the machine started working again in the afternoon. Another heavy-duty drilling machine requisitioned from Indore in Madhya Pradesh is likely to reach the tunnel site later on Saturday. (ANI)
