A massive glacier breach in Uttarakhand's Chamoli district caused flash floods in the Dhauli Ganga river, causing large-scale devastation in the upper reaches of the ecological fragile Himalayas. As per reports, a part of the Nanda Devi glacier broke off at Joshimath in Uttarakhand’s Chamoli leading to wide-spread devastation. Over 150 people, mostly labourers who were working at a power project in Tapovan-Reni are feared dead. Three bodies have been were recovered so far. Also, the power project was swept away completely, added state Director General of Police Ashok Kumar while describing the situation as under control. Homes along the way were also swept away as the waters rushed down the mountainsides in a raging torrent. Meanwhile, rescue operations by the state administration are underway. 

2 teams of NDRF are enroute and 3 additional teams have been flown in from Hindon which will reach the spot later in the night. 

More than 200 ITBP personnel are on the spot, and one column and Engineering Task Force (ETF) of Army, with all rescue equipment have been deployed.

IMD informed during the meeting that there is no rainfall warning in the region for the next two days.

Uttarakhand is facing a disaster. I am in touch with State CM Trivendra Rawat, Union Home Minister and NDRF officers. The rescue operations are underway, PM Modi said while addressing a rally in Haldia, West Bengal.

Seven Indian Navy Diving Teams are on standby for Uttarakhand flash flood relief operations, says Indian Navy officials.

Over 150 labourers working at a power project in Tapovan-Reni are feared dead, an Indo Tibetan Border Police spokesperson said while quoting the project-in charge. There were fears of damage in human settlements downstream, including in heavily populated areas.

Many villages were evacuated and people taken to safer areas.

Connectivity with some border posts was "totally restricted" due to a bridge collapsing near Reni village, an ITBP spokesperson said.

Several districts, including Pauri, Tehri, Rudraprayag, Haridwar and Dehradun, that were likely to be affected were put on high alert and forces of the ITBP and the National Disaster Response Force (NDRF) rushed in to help with the rescue and relief effort.
