The flight originated in
Niš, Serbia and was bound for
Dhaka, Bangladesh, with stops in Jordan, Saudi Arabia, and India. The aircraft departed from Niš at 18:36 UTC, with some 11 tonnes of ammunition on board, scheduled to arrive at Dhaka. Intermediate stops were planned in
Amman,
Riyadh and
Ahmedabad. Eyewitness accounts and video showed that the plane was on fire before it crashed. Secondary explosions were heard for up to two hours after the crash. Residents within a radius were advised to close windows and stay indoors, while emergency responders, explosives experts and staff from the
Greek Atomic Energy Commission were unable to inspect the wreckage due to uncertainty about the nature and state of any remaining cargo and residues. Drones were used instead to examine the wreckage. ==Weapons destination==
