As soon as the information about the collapse of a portion of an under-construction tunnel on Yamunotri national highway in Uttarkashi district, Uttarakhand, was received at the PMO on November 12, Mishra informed Prime Minister Narendra Modi, officials said.
Forty-one workers who found themselves trapped inside the under-construction Silkyara-Barkot tunnel on September 12 were hours away from freedom after rescuers managed to reach them on Tuesday. All that remains is pulling the men safely out though rescue pipes, which could take a couple of hours.
