Most pass relatively peacefully, though 18 arrests are made in New York. Groups calling for a review of immigration and asylum laws in Europe hold simultaneous demonstration in nine countries across the continent. The action is timed to coincide with European Council Summit in Tampere, Finland. Activists in Frankfurt shut down the airport for six hours by attaching foil-covered balloons filled with helium to fences, thereby interfering with radar. Demonstrators set up a media centre in Tampere to galvanise the groups and distribute digital pictures and eyewitness accounts over the internet.
Protesters manage to delay the summit for six hours.
Police use tear gas to break-up the demonstrations and there are hundreds of arrests. In London crowds congregate around Euston station. Police surround the protesters and make many arrests. Police react much more quickly than in Seattle, moving in with tear gas, billy clubs and motor cycles. Demonstrators fail to prevent or delay the meeting and eventually compromise by agreeing to the voluntary mass arrest of 600 of them.
