BAGHDAD, Iraq: Iraq has executed an Al-Qaeda terrorist, found guilty of taking part in the killing of the leader of the Supreme Council for the Islamic Revolution in Iraq Ayatullah Sayed Muhammad Baqer Al-Hakim, who also confessed to helping slay 19 Italians, an Iraqi justice official said.

The Justice Ministry Under Secretary Busho Ibrahim said Oras Abdul-Aziz Mahmood was hanged on Tuesday for his part in the April 2003 car bombing that martyred Al-Hakim and over 100 others at the holy shrine of Imam Ali in Najaf.

Ibrahim said Mahmood, who also went by the name Abu Omar al-Kurdi, had also admitted involvement in a 2003 attack on Italian forces in Nassiriya.

Mahmood, from Mosul in northern Iraq, was detained by US forces in 2005, found guilty and sentenced in October 2006.

He was handed over to Iraqi authorities last month.
