The protesters say President Kurmanbek Bakiev has failed to deliver on promises to tackle corruption and undertake key reforms.
Earlier today, the Kyrgyz parliament failed to meet in an emergency session to discuss the current protest movement and the opposition's demands.
Lawmakers are scheduled to start discussing next week amendments and addenda to the constitution drawn up by a working group led by Prime Minister Almaz Atambaev.

RFE/RL's Kyrgyz Service on April 12 asked participants in the protest rally on Bishkek's Alatoo Square why they had come out into the streets.
"We want to change the political system and to build the worthy future for young people. That is why we came here."
"I came here to seek fairness. I was taken to the court and accused of mudslinging."
"To improve the life of the people, we must change the constitution. We demand an early presidential election."
"If Bakiev was able to keep his promises and make reforms people would not come to the street. But he hasn't done anything and it forced people to come to the rally. We are strongly against the current government"
"We must change the existing system. This is very important."
"I came here to express my concern about the demolition of the Kulov-Bakiev tandem. I'm a mother of 10 children, with 30 grandchildren, and I am very much worried about their future."
"If Bakiev is following Akaev's path, then let him go away. Otherwise, he should take care of people and raise the youth. The future belongs to the young generation."
