Nepal tunnel rescuers seek trapped workers but hit dead ends

Nepali rescuers face Wednesday major setbacks and dead ends a week after devastating flash floods trapped dozens of hydropower workers inside mud-choked tunnels.

Crews have recovered at least three bodies, and while hundreds have been rescued overall, heavy sludge and blocked passages continue to hinder progress. The government had said initially it believed that more than 100 workers could be alive inside multiple tunnels.
