The United Nations Climate Change Conference (Cop15) turned ugly today when police officers beat back hundreds of demonstrators, including a group of 50 to 100 delegates that were trying to meet with the protesters.

More than 250 people were arrested, including spokespeople for Climate Justice Action (CJA), a global network of NGOs that organized a walkout at the Bella Center today. CJA’s spokesperson Dan Glall told Mantoe Phakathi at Inter Press Service that “as a condition for going back to the negotiations, we demand industrialized nations uphold the Kyoto Protocol, commit adequate funds to adaptation and reduce greenhouse gas emissions significantly.”
