Dozens of people have been killed after a passenger plane carrying 71 people from Bangladesh crashed and burst into flames as it landed in Kathmandu, Nepal’s capital.

The death toll among those on board the US-Bangla Airlines flight remained unclear amid the chaos of the crash, with badly injured victims being rushed to nearby hospitals.

Nepal army spokesman Brigadier General Gokul Bhandari said 50 people had died and the fate of the others was unknown.

A police official said at least 38 people had died, 23 were injured and another 10 were unaccounted for.

An AP journalist who arrived at the scene soon after the crash saw the US-Bangla Airlines twin-propeller plane broken into several large pieces, with dozens of firefighters and rescue workers clustered around the wreckage in a grassy field near the runway.

Hundreds of people stood on a nearby hill, staring down at what remained of the Bombardier Dash 8.

The plane swerved repeatedly as it prepared to land in Kathmandu, said Amanda Summers, an American citizen working in Nepal. The crowded city sits in a valley in the Himalayan foothills.

“It was flying so low I thought it was going to run into the mountains,” said Ms Summers, who watched the crash from the terrace of her home office, not far from the airport. “All of a sudden there was a blast and then another blast.”

Fire crews put out the flames quickly, perhaps within a minute, she said, though for a time clouds of thick, dark smoke rose into the sky above the city.

The plane had circled the airport twice as it waited for clearance to land, Mohammed Selim, the airline’s manager in Kathmandu, told Dhaka-based Somoy TV station by telephone.

US-Bangla Airlines operates Boeing 737-800 and smaller Bombardier Dash 8 Q-400 planes.

The airline, part of US-Bangla Group, is based in the Bangladeshi capital, Dhaka, and flies to several domestic and international destinations. The parent company is involved in a number of industries, including real estate, education and agriculture.

Kathmandu’s airport has been the site of several deadly crashes. In September 2012, a Sita Air turboprop plane carrying trekkers to Mount Everest hit a bird and crashed shortly after takeoff, killing all 19 on board.
