Chidiac was seriously injured on 25 September 2005, by a car bomb in Jounieh, Lebanon. The bomb which nearly killed her was a one-pound device, detonated as she entered her car. Her left leg below the knee was blown off and her hair and clothes were set on fire. She was in stable condition following the amputation of her severely injured left arm. The blast was one of a series of bombings in Lebanon mostly targeting critics of Syria, but including the centrist Lebanese defense minister, Elias Murr.
