Protesters were told over police loudspeakers that they were being contained "in the interests of preventing damage to property".
Several times elements of the crowd surged forward, trying to push through the riot police lines. There were a series of minor scuffles and missiles were hurled at police.
A number of people suffered minor injuries and the police arrested more than 20 people.
