Some of the 40 workers trapped for days in a collapsed road tunnel in northern India have become ill as falling debris and technical glitches delayed work to free them, officials said.

Rescuers have been trying to drill through the rubble and insert wide steel pipes to free the construction workers who have been trapped since Sunday when a portion of the tunnel they were working on collapsed in the mountainous state of Uttarakhand.
