Rejoicing, rioting and recriminations
The disturbances, which resulted in the arrest of 28 people, came at the end of a largely peaceful day of protest on Saturday as Ireland hosted the formal celebrations for the single biggest expansion of the EU in its 47-year history.
Violence erupted as a march organised by the anti-globalisation group Dublin Grassroots Network attempted to approach the Ashtown Gate entrance to the Phoenix Park from the Navan Road.
