Sheikh Hassan Nasrallah has been re-elected as Hizbullah's leader for a sixth term, according to the guerilla group.
The statement said Sheikh Naim Qassem was also re-elected as the group's deputy leader.
Although elections to determine Hizbullah's leadership are usually held every three years, they were last held in 2004. A Hizbullah official said the two-year delay was caused by internal Lebanese differences and the 2006 Second Lebanon War.
Nasrallah has led Hizbullah since his predecessor was killed by Israel in 1992.
