Abdul Salam Arif
Qāsim was assassinated in February 1963, when the Ba'ath Party took power under the leadership of General Ahmed Hassan al-Bakr (prime minister) and Colonel Abdul Salam Arif (president). In June 1963, Syria, which by then had also fallen under Ba'athist rule, took part in the Iraqi military campaign against the Kurds by providing aircraft, armoured vehicles and a force of 6,000 soldiers. Several months later, `Abd as-Salam Muhammad `Arif led a successful coup against the Ba'ath government. Arif declared a ceasefire in February 1964 which provoked a split among Kurdish urban radicals on one hand and Peshmerga (Freedom fighters) forces led by Barzani on the other.
