A demonstration organised by Muslim group United Ummah, formerly Muslims Against Crusades (M.A.C), is taking place outside the U.S. Embassy today between 12 and 2pm.
Police are expecting between 200 and 300 protesters.
Also, separate to the main demo, one main is holding a 6 day vigil for Pakistan soldiers killed by NATO forces.
As the protest continued, more and more police were in attendance.
By 1:00pm the number of protesters had increased with small groups of protesters dotted around the square.
Shortly after, the police surrounded the main demo with reportedly hundreds more police around.
