Rescuers in India tunnel collapse change approach as frantic efforts pass one-week mark
Indian authorities are exploring new ways to rescue 40 construction workers trapped underground for more than a week.
The workers became stranded when a highway tunnel they were building partially collapsed in the northern state of Uttarakhand last Sunday.
Although they are being supplied with food and water, a doctor said some of the men were getting ill, and had been vomiting and getting headaches.
