More now on the Nepali army’s rescue operation to save about 100 people trapped in a tunnel at a hydropower project swamped by Wednesday’s flooding.

“Two helicopters have been dispatched but it is challenging because it is tough to even locate the entry points of the tunnel,” army spokesperson Raja Ram Basnet told AFP.

Relief efforts are also under way to provide the rescued people what they need.

The army is still working to safely evacuate more than 100 people trapped in the same tunnel.
