Rescue workers pull bodies out of plane wreckage at Kathmandu airport

Crash The passenger flight from Dhaka Bangladesh landed in Kathmandu Nepal but ended up careening off the runway and crashing in a nearby field

"We are yet to ascertain the reason behind the unusual landing", he said suspecting the aircraft might have sustained some technical glitches.

"It was flying so low I thought it was going to run into the mountains", said Summers, who watched the crash from the terrace of her home office, not far from the airport.

The air crash has been regarded as a big shot to the tourism industry of the Himalayan nation, which is still recovering after the deadly quake of 2015 killed almost 9,000 people.

General Manager Rajkumar Chhetri said the US-Bangla plane crashed at Kathmandu airport due to missed approach.

A massive rescue operation was launched with help from Nepal army personnel.

Survivor Sanam Shakya, who climbed out of a window of the smouldering plane, said he didn t realise the aircraft was in trouble until it hit the ground.

There is silence for a while, then a "Fire One" calls the tower, indicating that a crash has occurred and the airport fire tender has been activated.

The exact number of dead and injured remained unclear amid the chaos of the crash and the rush of badly injured people to nearby hospitals, but Brig.

One witness said on Twitter: "An Airplane just crashed at the Kathmandu International Airport".

The plane, operated by US-Bangla Airlines, was on a flight from Bangladesh capital Dhaka. The National Transportation Safety Board concluded that pilot error, including the response by the captain, was the main cause of the accident.

Dhaka and Kathmandu have been connected by air since the days of East Pakistan, when DC-3 piston-engine aircraft of Pakistan International Airlines (PIA) flew the route.

The plane was carrying 67 passengers and four crew.

FlightRadar24 said the aircraft involved is a "17-year-old Bombardier Dash 8 Q400".

"I saw the plane make a sharp turn over the terminal back towards south and then disappeared towards the runway".

The injured are receiving treatment at local hospitals in Kathmandu.

There have been many aviation incidents in Nepal but this is the deadliest since a Pakistan International Airlines plane crashed on approach in September 1992, killing all 167 on board.

In July 2016, the airline announced plans to phase in its first two Boeing 737-800 aircraft in September of the same year and to subsequently launched new worldwide routes, for example to Singapore and Dubai by the end of 2016. There were no reports of injuries.
