BEIRUT: Unidentified gunmen shot out the windows of a KFC fast food establishment in Nabatieh, south Lebanon early Wednesday.

Police and Lebanese Army intelligence have opened a probe into the shooting, which took place at 3:30 a.m.

Last week, protesters – angered by a U.S.-made film insulting Islam's Prophet Mohammad – vandalized American fast food restaurants KFC and Hardee’s in Tripoli, north Lebanon, and set them on fire.

The protesters also clashed with security forces following Friday prayers. One demonstrator was killed and 27 people, including 12 policemen and a Lebanese Army soldier, were injured.

The anti-Islam film "Innocence of Muslims" has touched off protests across the Muslim world.
