Right now, cars are burning on Nassau St as rioters protesting against the "Love Ulster" parade (something about gay rights in Northern Ireland I think) are running amok. I thought it would be an idea to keep an eye on the Irish Times' webcam in case I saw something interesting.
I think the yellow jacketed figures are the police. As you can see O'Connell Bridge and the Quays have been have been cleared of traffic, only essential riot-related vehicles like Foster's Beer Tankers are being allowed to enter!
