The Tahrir square in Egypt played very important role in latest protest against government. A political organization Hizbut Tahrir named liberty roundabout as Tahrir Square.
The organization distributed massive pamphlets in Lahore in which they demand to hang Raymond Davis, push out blackwater agents, end war against Islam and suspend NATO lines. They also want to Establish Khilafah in Pakistan.
They announced to organize a protest on 6 March. We are unable to get timings of this protest, most probably it will be in day time. We also see a facebook page regarding this issue.
