Bosnian state prosecutor has ordered an investigation after the report that an aircraft operating between Zagreb and Sarajevo was damaged by what looks like a firearm bullet.

The investigation will be carried out in presence of the Bosnian Civil Aviation Directorate officers.

The damage was reported following the regular inspection of the plane at the Sarajevo International Airport.

The observed damage has not jeopardised the safety of the flight or passengers in any way, and a detailed examination will determine the manner of the damage, as well as the safety of the aircraft for further flights, said the Prosecutor's Office.
