The terror group Hizbullah group said that Sheikh Hassan Nasrallah has been re-elected as the group's leader for a sixth term. A Hizbullah statement Thursday did not say when top Hizbullah officials voted to re-elect Nasrallah as the group's secretary-general. The statement said Naim Kassem also has been re-elected as the group's deputy leader. Hizbullah's leadership elections are usually held every three years but 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. The official spoke on condition of anonymity because he was not authorized to speak to the media. Nasrallah has led Hizbullah since his predecessor was killed by Israel in 1992.
