Near an airport in central Nepal, a plane carrying 72 people crashed, and authorities say at least 40 bodies have been found.
A Yeti Airlines flight from Kathmandu to the popular tourist destination of Pokhara crashed and caught fire as it touched down.

Hundreds of Nepalese soldiers are involved in the operation at the crash site in the gorge of the Seti River, just one and a half kilometres from the airport.

Of the passengers, 53 are said to be Nepalese. There were five Indian, four Russians and two Koreans on the plane. There was also one passenger each from Ireland, Australia, Argentina and France among others.
Aviation accidents are not uncommon in Nepal, often due to its remote runways and sudden weather changes that can make for hazardous conditions.

In early 2018, 51 people were killed when a US-Bangla flight travelling from Dhaka in Bangladesh caught fire as it landed in Kathmandu.
