On 27 June, three months after the Saur Revolution, Amin outmaneuvered the Parchamites at a Central Committee meeting, giving the Khalqists exclusive right over formulating and deciding policy. A purge against the Parchamites was initiated by Amin and supported by Taraki on 1 July 1979. Karmal, fearing for his safety, went into hiding in one of his Soviet friends' homes. Karmal tried to contact Alexander Puzanov, the Soviet ambassador to Afghanistan, to talk about the situation. Puzanov refused, and revealed Karmal's location to Amin. The Soviets probably saved Karmal's life by sending him to the Socialist Republic of Czechoslovakia. In exile, Karmal established a network with the remaining Parchamites in government. A coup to overthrow Amin was planned for 4 September 1979. Its leading members in Afghanistan were Qadir and the Army Chief of Staff General Shahpur Ahmedzai. The coup was planned for the Festival of Eid, in anticipation of relaxed military vigilance. The conspiracy failed when the Afghan ambassador to India told the Afghan leadership about the plan. Another purge was initiated, and Parchamite ambassadors were recalled. Few returned to Afghanistan; Karmal and Mohammad Najibullah stayed in their respective countries. The Soviets decided that Amin should be removed to make way for a Karmal-Taraki coalition government. However Amin managed to order the arrest and later the murder of Taraki.
