Example Input: Question: Who fought in the Nagorno-Karabakh War? Passage:Aram Sarkissian (Simon Abkarian) is a young French-Armenian member of AGJSA, an Armenian militant organization, who leaves his family in Paris to fight in the Nagorno-Karabakh War. In October 1993, Aram returns to France to live a "normal life" again, but finds his younger brother Levon (Mathieu Demy) preparing the assassination of Azbalan Djelik, a general of the Turkish Army visiting France. Aram opposes the assassination, claiming the Armenian struggle lies in Nagorno-Karabakh, however, Levon considers Aram to be a coward, who then reluctantly agrees. One evening, General Djelik is killed when his car is ambushed by 3 masked gunmen, who shoot and kill three of the four passengers. The survivor, Djelik's aide-de-camp Colonel Talaat Sonlez (Serge Avédikian), shoots Levon after he pretended to be dead. Levon is immobilized and enters a coma, and Sonlez is shot by the Armenians before they flee. AGJSA claims responsibility for the attack, justifying it as General Djelik was a high-ranking member of the Black Wolves, a Turkish ultranationalist organization. Talaat survives again, and searches for the assassins by asking Monsieur Paul (Gilles Arbona), a French counter-terrorism policeman monitoring the activities of AGJSA, who does not reveal their identities.
