Hundreds of activists were detained Saturday in Copenhagen outside a climate conference among industrial members of the United Nations, MSNBC reported.
Police arrested 968 people who had gathered at the rear of the rally, part of a worldwide "Day of Action."
The protesters were demanding a resolution on climate-change that would reduce gas emissions and aid developing countries hurt by pollution.
Four cars had been set on fire during the evening, police said. One of the protesters was injured by fireworks, and one police officer reported minor injuries after being hit with a rock thrown by one of the protesters.
Most of the detained protesters were released. Five were charged, however, and are scheduled in court on Sunday.
The rally centered around the Bella Center where the summit was taking place, CNN reported.
Police spokesman Rasmus Bernt Skovsgaard said that "there was some cobblestone-throwing and at the same time people were putting on masks. We decided to go for preventive detentions to give the peaceful demonstration the possibility to move on."
Some demonstrators argued police abuse, after police detained 400 protesters by typing their hands behind their backs and forcing them to sit on the street in freezing temperatures.
The countries are expected to reach an agreement by Friday, which is the end of the two-week summit.
