At least 14 people have died and 150 missing after apiece of a Himalayan glacier fell into a river and triggered a huge flood in northern India.
The floodwaters burst open a dam and a deluge of water poured through a valley in the state of Uttarakhand.
Most of the missing are believed to be workers from two hydro power plants in the area.
Hundreds of troops, paramilitaries and military helicopters have been sent to the region to help with rescue efforts. Experts are investigating the incident though it is not yet clear what might have caused the glacial burst. Officials say 25 people have been rescued so far.
Indian Prime Minister Narendra Modi tweeted on Sunday, saying he was keeping a close watch on the situation in Uttarakhand.
“Have been continuously speaking to authorities and getting updates on… deployment, rescue work and relief operations,” he said in a tweet.
“India stands with Uttarakhand and the nation prays for everyone’s safety there.”
Leaders from all over the world have also sent their condolences to families of the victims.
“My thoughts are with the people of India and rescue workers in Uttarakhand as they respond to devastating flooding from the glacier collapse,” tweeted UK Prime Minister Boris Johnson.
“The UK stands in solidarity with India and is ready to offer any support needed.”
