Heavy machinery has been brought in to pull out nearly 40 workers trapped inside the highway tunnel in the Himalayan state of Uttarakhand. Excavators have begun drilling with heavy machinery to fix a wide steel pipe that will help pull out almost 40 Indian workers trapped inside a collapsed Himalayan highway tunnel that caved in two days ago in the north Indian state of Uttarakhand. Patwal said it was not easy to ascertain the time required to pull out the workers. A team of geologists from the state government and educational institutions had arrived to determine the cause of the accident, he added. Photographs released by government rescue teams soon after the collapse showed huge piles of rubble blocking the wide tunnel, with twisted metal bars from its roof poking down in front of slabs of concrete.
