Two persons have died and around 30 people are feared buried after a landslide in Himachal Pradesh's Kinnaur left many vehicles trapped under debris this afternoon.

The landslide took place on the Reckong Peo-Shimla Highway in Kinnaur at around 12:45 pm today. A bus of the Himachal road transport corporation, a truck and other vehicles were buried under the rocks and mud that hurtled down, an ITMP official tweeted. He also tweeted dome photos of the landslide.

Reports suggest the bus, travelling to Shimla, had 40 people on board. The local police said 25-30 people were trapped or buried. Ten people have been rescued including the driver, reports say.

A video showed boulders and rocks rolling down the hillside with a crashing sound and blocking the highway.

Teams of the Indo-Tibetan Border Police (ITBP) were sent to the area for the rescue. Chief Minister Jai Ram Thakur said the National Disaster Response Force (NDRF) had also been called in.

"I've directed the police and the local administration to carry out rescue operations. NDRF has also been put on alert. We have received information that one bus and a car could have been hit. We are waiting for detailed information," Mr Thakur told reporters.
