A domestic plane slipped off the runway and crashed Wednesday while trying to take off from the airport serving Nepal's capital, killing the 18 passengers and injuring the pilot.

Police official Basanta Rajauri said authorities have pulled out all 18 bodies. The only survivor was the pilot, who was taken to Kathmandu Medical College Hospital for treatment, said a doctor at the hospital who was not authorized to speak to media.

The pilot has injuries to the eyes but is not in any danger, the doctor said.

The Saurya Airlines plane was heading from Kathmandu to the resort town of Pokhara.

It was not clear how it slipped.

Local media images showed smoke rising and plane wreckage scattered all over a ditch. A fire has been brought under control.

Tribhuvan International Airport, the main airport in Nepal for international and domestic flights, has been closed as emergency crew worked.

It is monsoon rainy season in Kathmandu but was not raining at the time of the crash. Visibility was low across the capital, however.

Saurya Airlines operates the Bombardier CRJ 200 on domestic routes.

In 2019, a Bangladeshi airliner crashed at Tribhuvan airport, killing 51 people while 20 on board survived. An investigation confirmed the plane was misaligned with the runway and its pilot was disoriented and tried to land in “sheer desperation” when the plane crashed.

In 2015, a Turkish Airlines jet landing in dense fog skidded off a slippery runway at the airport. The plane was carrying 238 people but there were no serious injuries.
