Police officers fired tear gas and wielded batons on Wednesday to beat back hundreds of demonstrators outside the global climate meeting here, as a police spokesman said 250 people had been arrested.
Police clash with protesters at a roadblock near the venue of the United Nations Climate Change Conference in Copenhagen on Wednesday.
The police tried to disperse the chanting, drum-beating protesters who had marched from a train station about a mile away to try to make their way to the Bella Center, where representatives from nearly 200 countries are meeting to try to reach an accord on climate change. A group of 50 to 100 delegates emerged from the convention center, seeking to meet with the protesters, but they, too, were driven back by the police.
