Bangladeshi airline made emergency landing after a passenger suspected of attempting to hijack the flight from Bangladesh to Dubai, local media reported.
The suspect, who reportedly warned he had pistol, was shot dead in aerial clashes with the local security forces after it made an emergency landing in Chittagong.
It is not yet clear the suspect may have attempted to hijack the flight with 148 passengers and crew on board.
All passengers and flight crew on board the Biman Bangladesh Airlines Flight BG147 disembarked safely.
Army officials said the man, believed to be aged 25, was initially wounded when shots were fired on Sunday but died shortly afterwards, AFP news agency reports.
“We tried to arrest him or get him to surrender but he refused and then we shot him,” Maj Gen Motiur Rahman told reporters.
“He is a Bangladeshi. We found a pistol from him and nothing else,” he added.
Earlier reports suggested that the suspect may have been mentally ill and had demanded to speak with Bangladeshi Prime Minister Sheikh Hasina, who was visiting the coastal city of Chittagong.
