At first there were reports that no water canons were used! that was a lie, and to any agency while in uniform and or on the clock being paid whom reported those statements should face disciplinary actions.
There are other reports that rubber bullets/tear gas/ concussion grenades were also used.
Live feeds are being reported as shut down.
In almost every report I have read it has stated ” Peaceful Protestors Are being attacked “
They even tried to take the Drone out (See end of video) Below
