Hassan Nasrallah (; born 31 August 1960) has been the third Secretary General of the Lebanese political and paramilitary organization Hezbollah since his predecessor, Abbas al-Musawi, was assassinated by the Israel Defense Forces in February 1992. Hezbollah has since been designated a terrorist organization, either wholly or in part, by the United States, European Union and other nations. Nasrallah is often referred to as "al-Sayyid Hassan" , the honorific "Sayyid" denoting descent from the Islamic prophet Muhammad through his grandson Husain ibn Ali.
