The demonstrators, led by opposition Civil Contract Party member and National Assembly Yelk Faction head Nikol Pashinyan, entered the Armenian State Pedagogical University, in Yerevan.
"We call for a boycott of classes," Pashinyan said.
Subsequently, the demonstrators chanted and went up the university floors.
"You went in, saw that the door is open. Whoever wanted to join [you] has joined you. [Now] come out; we’ll continue our work," News.am cited a university representative as saying.
Since Monday morning, the demonstrators have blocked numerous streets in downtown Yerevan.
As reported earlier, Nikol Pashinyan yesterday had called on people to block Yerevan’s bridges, streets, and subway.
