Taraki was instructed to stop-over in Moscow, where the Soviet leaders urged him to remove Amin from power as per the KGB's decision, because Amin posed danger. Amin's trusted aid, Daoud Taroon, informed Amin of the meeting and the KGB's plan. In Kabul, Taraki's aides, the Gang of Four (consisting of Watanjar, Mazdoryar, Gulabzoi and Sarwari), planned to assassinate Amin but failed as Amin was informed of their plot. Within hours of Taraki's return to Kabul on 11 September, Taraki convened the cabinet "ostensibly to report on the Havana Summit". Instead of reporting on the summit, Taraki tried to dismiss Amin as Prime Minister. Amin, aware of the murder plot, demanded the Gang of Four to be removed from their posts, but Taraki laughed it off. Taraki sought to neutralise Amin's power and influence by requesting that he serve overseas as an ambassador. Amin turned down the proposal, shouting "You are the one who should quit! Because of drink and old age you have taken leave of your senses."
