Rescuers are working around the clock Tuesday to remove debris to extract 40 workers who have been trapped for over two days after an under-construction tunnel collapsed in northern India. Officials hope to extricate them in the next 24 hours.
A 2.5-foot (0.76 meter)-wide steel pipe will be pushed through an opening of excavated debris with the help of hydraulic jacks to safely pull out the stranded workers, authorities said.
