Hundreds of cyclists took to Dublin's streets Friday, in the largest Critical Mass the city had ever seen. The following day thousands of anarchists, workers and anti-capitalists took to the streets in a number of actions and marches in opposition to borders and capitalism. Police used a water cannon against demonstrators; it was the first time one had been used in the South. The cannon had to be borrowed in advance from Northern Ireland. Dublin is the new seat of the European Union which was meeting Saturday. Pictures, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
