At least 15 persons have been killed and 160 are feared missing after a portion of the Nanda Devi glacier broke off in Uttarakhand’s Chamoli district on Sunday. Indian Air Force teams left for the avalanche-hit areas of Uttarakhand’s Chamoli district early on Monday to ramp up relief efforts. The efforts are focussed at the moment on rescuing 30-35 people trapped in a 250-metre long tunnel at Tapovan, Uttarakahnd DGP Ashok Kumar said.
