On 8 February 1963, a military coup in Iraq led by a Ba'athist–Nasserist alliance toppled Qasim, who was subsequently shot dead. Abdel Salam Aref, a Nasserist, was chosen to be the new president. A similar alliance toppled the Syrian government on 8 March. On 14 March, the new Iraqi and Syrian governments sent Nasser delegations to push for a new Arab union. At the meeting, Nasser lambasted the Ba'athists for "facilitating" Syria's split from the UAR, and asserted that he was the "leader of the Arabs". A transitional unity agreement stipulating a federal system was signed by the parties on 17 April and the new union was set to be established in May 1965. However, the agreement fell apart weeks later when Syria's Ba'athists purged Nasser's supporters from the officers corps. A failed counter-coup by a Nasserist colonel followed, after which Nasser condemned the Ba'athists as "fascists".
