In the midst of political turmoil in Azerbaijan, Yaqub Mammadov, then the rector of Azerbaijan Medical University, was elected the Chairman of Supreme Soviet of Azerbaijan on 5 March during the extraordinary session of the parliament related to the Khojaly massacre of Azerbaijani civilians in Nagorno-Karabakh region of Azerbaijan after the speaker of the parliament, Elmira Gafarova resigned from her post.[2] On 6 March, President Ayaz Mutallibov was forced to resign and according to the Azerbaijani constitution of the period, speaker of the parliament, Yagub Mammadov assumed the presidential duties and responsibilities until the new elections.[3] [4] While acting as the President of Azerbaijan, Mammadov met with Levon Ter-Petrosyan in Tehran in an effort to start peace talks mediated by Iran. On 8 May, when the Tehran Communiqué between Ter-Petrosian and Mammadov was signed, Armenian forces captured Shusha.[5] In his interviews, Mammadov always refused to assume any responsibility for the loss of Shusha.[6]
On 14 May, the former President Mutalibov returned to power after the parliament relieved him off the responsibility for the Khojaly Massacre, but was ousted by the armed revolt led by Azerbaijan Popular Front on 15 May.
