The flight took off from Dhaka and was en route to Dubai.
An alleged hijacker was shot dead in a military operation at Chittagong airport in Bangladesh on Sunday evening after a Biman Bangladesh flight from Dhaka to Dubai made an emergency landing and five crewmembers and all the 142 passengers were evacuated. "They took action. He was brought out injured, but later died", Rahman said, according to the Bangladeshi newspaper the Daily Star.
The suspect, a Bangladeshi, asked to speak to the country's Prime Minister before dying from injuries sustained in an exchange of gunfire with military commandos, according to officials. Rahman described the suspect as a "terrorist".
Rahman declined to provide more details about the incident, but said that everyone on the plane was safe. Reports suggest that at least two members of the flight crew are being held hostage on the plane at Shah Amanat International Airport.
The suspect, who reportedly claimed to be carrying a pistol, was killed when security forces stormed the plane after it made an emergency landing in Chittagong, BBC reported on Sunday. "We have to investigate how the man could board the aircraft in Dhaka with a gun or something that looked like a gun". The man also opened fire as he tried to enter the cockpit of the plane.
The suspect appeared to be "mentally imbalanced", said Air Vice Marshal M. Naim Hassan, chairman of the Civil Aviation Authority. "The situation at Shah Amanat global airport is very much under the control of the Bangladeshi army", he said.
The security questions are a matter of concern and would be the subject of an investigation, said the aviation official.
That attack prompted a swift crackdown by Prime Minister Hasina, with hundreds of suspected militants and their sympathisers arrested or killed in raids across the country.
