The escalation in Yerevan occurred when the opposition learned that President and Premier refuse to seal the fate of Onik Gasparyan, the Chief of Staff of Armenia's Armed Forces. Gasparyan and a large group of military officer have been supporting the resignation of Premier Nikol Pashinyan.
President Armen Sarkisyan did not send Prime Minister's decree about Gasparyan's resignation to the Constitutional Court. So, the constitutional nature of the document was not checked.
According to Sputnik Armenia, President Sarkisyan left this issue up to Prime Minister Pashinyan.
"The matter of resignation of (...) Gasparyan lies within competence and consideration of Prime Minister - both in terms of legal procedure and constitutional consistency and political consequences", reads Sarkisyan's reply to the letter of Ara Zograbyan, the Head of Chamber of Lawyers of Armenia.
Vazgen Manukyan, the opposition leader urged people to block all entrances and exits from the Parliament building. The opposition believes they managed to protect Gasparyan.
On Tuesday evening, hundreds of armed law enforcers reached the site. Rally members built a barricade, using trash bins. Ishkhan Sagatelyan, one of the opposition leaders said the protesters are ready to block other governmental buildings. Activists claimed they'd stay until Pashinyan resigns. Sagatelyan also offered Pashinyan to arrive in the Parliament until Wednesday noon and resign, and then the opposition would agree on election.
The opposition also assumes that the police could "cleanse" two central avenues leading to the Parliament, to prevent it from the blockade.
On February 25, Gasparyan urged Prime Minister Pashinyan to resign. Pashinyan, in turn, blamed Chief of the General Staff for the attempt of coup d'etat in Armenia. Then, he asked Sarkisyan to fire Gasparyan but the President refused.
