Islamic Dawa Party
In 1979, Aziz became Deputy Prime Minister of Iraq, and worked as a diplomat to explain Iraq's policies to the world. In April 1980 he survived an Iranian-backed assassination attempt carried out by members of the Islamic Dawa Party. In the attack, members of Islamic Dawa Party threw a grenade at Aziz in central Baghdad. The attack killed several people. It was part of the "casus belli" of the Iran–Iraq War.
