A Serbian activist on Wednesday threw a pie in the face of French intellectual Bernard-Henri Levy at a showing of his film "Peshmerga" in Belgrade.
The film about the Kurds' battle against the Islamic State group was being shown at the Beldocs documentary festival in the city when Levy was ambushed by a member of the small communist group SKOJ, the state-run Tanjug news agency reported.
As Levy addressed the audience, the young man ran in front of him and threw the pie in his face. Two others, claiming to be members of the SKOJ, shouted: "Murderer, leave Belgrade!"
During the 1990s, Levy strongly criticised the siege of the Bosnian capital Sarajevo by Serb forces and was a powerful voice against the regime of the then Serbian strongman Slobodan Milosevic.
"This man was advocating the bombing of Yugoslavia eight years before NATO strikes" against Serbia in 1999, the activists told the audience.
Levy responded by telling the activists in French "long live democracy in Belgrade".
Security guards then escorted the SKOJ activists from the cinema.
Many Serbs reproach Levy for his support of Muslims during Bosnia's 1992-1995 war between its Croats, Muslims and Serbs which claimed around 100,000 lives.
