Sheikh Naim Qassem, Hezbollah’s successor to slain head Hassan Nasrallah.
Qassem was appointed deputy chief in 1991 by the armed group’s then-secretary general Abbas al-Musawi, who was killed by an Israeli helicopter attack the following year.
Born in 1953 in Beirut to a family from Lebanon’s south, Qassem’s political activism began with the Lebanese Shi’ite Amal Movement.
