The 41 workers trapped in a collapsed tunnel in Uttarakhand's Silkyara are expected to be rescued today - finally after 11 days. Only 12 metres of rock and debris separate them and rescue operation is expected to be over by 11:30 pm, officials said today. The under-construction tunnel had collapsed on November 12, trapping the labourers working inside. Advanced drilling machines were flown in as rescue officials raced against time to save the trapped workers.
