19 September Hundreds of protesters gathered for a rally outside government buildings in the capital
Yerevan denouncing Pashinyan as being soft on Azerbaijan and weak in Nagorno-Karabakh, including what Pashinyan characterized as calls for a ''
coup d'état'' and his removal from office. Pashinyan denounced such calls stating that "We must not allow certain people, certain forces to deal a blow to the Armenian state." The protesters were met by a police cordon, and clashed with the police in an attempt to storm the
Government House. The protesters and police exchanged glass bottles and stun grenades and several of the building's windows were smashed. Protesters also surrounded the
Russian embassy criticizing Russia's refusal to intervene in the conflict. Among the participants were members-elect of the
Yerevan City Council, elected two days prior during the
2023 Yerevan City Council election. After Russia complained that the security of their embassy was lacking and impacting its operations, Armenian police were sent to form a cordon around the embassy, resulting in a clash between the protesters and police. More than 30 people were reportedly injured.
20 September The crowd in
Republic Square began to number in the thousands with increasing calls for the removal of Pashinyan and for Armenia to intervene militarily, as it did during the
First Nagorno-Karabakh War. The police started detaining protesters, stating that the rally was illegal. Some protesters called for the rejection of the
Alma-Ata Protocol, and Armenia's withdrawal from the
Collective Security Treaty Organization (CSTO), which Pashinyan rejected, stating that such demands were "calls to abandon Armenia's independence."
21 September 84 people were detained during protests.
22 September Two unidentified assailants threw some bags of red paint at the gates of the Russian embassy in Yerevan. They were promptly removed by the Armenian Police. Levon Kocharyan, son of former Armenian President
Robert Kocharyan, was arrested after reportedly getting into a fistfight with four police officers while participating in protests.
24 September The
National Security Service announced it had thwarted a
coup attempt by the
Khachakirner militia, which had attempted to launch their own offensive into the
Lachin corridor, and had threatened to "take matters into their own hands" if the Armenian government did not launch a military operation against Azerbaijan.
25 September The Interior Ministry said more than 140 people had been arrested in Yerevan. Armenian special forces began detaining demonstrators who blocked roads in Yerevan. ==Aftermath==
