After a long day of demonstrations against the Canadian Tar Sands, and the issues of climate change and migration activists have been tear-gassed and arrested by police while attending an evening party.  The police appear to be trying to wear down street-level opposition through constant offensive action against activists.

In the early evening Naomi Klein addressed a Reclaim Power party in Christiania. Later in the evening, in unclear circumstances, the police arrived with a water cannon whilst a barricade had been built and fired tear gas [reports 1 | 2]. The situation spiralled, street fights broke out and the police entered Christiania, making numerous (200+) arrests [Photo 1 | 2 | 3] [Video 1 | 2 | 3].

Despite the successful protests of 14th December, where activists were able to march through the streets without mass arrests, it seems it is effectively illegal to publicly voice opposition to emissions trading, carbon markets, and other "solutions" to the problem of climate change in Copenhagen.  Over 1500 people have now been detained, arrested, beaten, tear-gassed, pepper-sprayed, and purposefully held in sub-zero temperatures for voicing their opposition. Despite this people remain committed to showing solidarity with the global south and taking direct action.
