Some of the 40 workers trapped for days in a collapsed road tunnel in northern India are getting sick, while falling debris and technical glitches delay the work to free them. Rescuers have been trying to drill through the rubble and insert wide steel pipes to free the construction workers. They have been trapped since Sunday when a portion of a tunnel collapsed in the mountainous Uttarakhand state. Progress has been slow because of falling debris and glitches with a drilling machine, but a more powerful machine has been sent. Rescuers have sent food and water through narrow channels to the workers, but some of them say they have begun to suffer from fevers and body aches.
