Over 100,000 protestors gathered in Copenhagen yesterday, in a historic protest, calling for a binding deal that would bring between 25- 40% emission cuts. The marches included co-operators and members of several NGO's from across the globe.

99% of the protestors, protested peacefully, however reports suggest a small part of the crowd began throwing stones at police officers. This was despite an extensive clean up of the streets, to remove anything that could be used as a missile, prior to the event.

The protestors present have hit back with harsh words aimed at the Danish police authority, after as many as 1000 people are thought to have been arrested amid clashes with riot police as the authorities used "kettling" tactics to contain marchers. Those throwing stones were pinned in along with innocent, peaceful protestors as arrests were made. Those detained complain that they have been held in freezing conditions, with no water and no toilets. The police handcuffed up to a thousand people and sat them in lines on the street, before transporting them in buses from the scene. People were left for several hours as the police struggled to get the transportation through the crowds.

Mel Evans from Climate Justice Action told the BBC "People were there in freezing conditions urinating on themselves and being held in lines like, essentially like animals."

Danish law bans protestors from wearing masks and it is believed that a small minority of the crowd decided to wear black masks, which may have sparked further police action.

The World Development Movement's director, Deborah Doane, has condemned the authorities for what she said was a "complete violation of the right to protest and a step towards the breakdown of democracy".
