A Bangladeshi airliner with 71 people on board crashed on Monday while coming in to land at the airport in the Nepali capital, Kathmandu, killing at least 50 people, an army spokesman told Reuters.
The plane was carrying 67 passengers and four crew members, an airport official said, adding that 17 people on board had been rescued.
Television images showed smoke rising from the crash site. Mountainous Nepal is notorious for air accidents. Small aircraft often run into trouble at provincial airstrips.
A Thai Airways flight from Bangkok crashed while trying to land in Kathmandu in 1992 killing all on board.
US-Bangla Airlines is a unit of the US-Bangla Group, a US Bangladeshi joint venture company.
The Bangladeshi carrier launched operations in July 2014 and operates Bombardier Inc and Boeing aircraft.
