Operation Labrador was a false flag operation carried out by the Yugoslav Air Force's Counterintelligence Service (KOS) in the Croatian capital city of Zagreb during the early stages of the Croatian War of Independence. It was devised as a series of terrorist attacks intended to create an image of Croatia as a pro-fascist state. Two bombings were carried out on 19 August 1991, with one at the Jewish Community Centre and a second near Jewish graves at the Mirogoj Cemetery; there were no casualties. Additional attacks targeted the national railway network and were designed to implicate the Croatian President. Operation Labrador was complemented by Operation Opera — a propaganda campaign devised by the KOS to feed disinformation to the media.
