Hundreds detained in Copenhagen at Climate Change Conference

Trouble has broken out as thousands of people marched through Copenhagen demanding action from leaders at UN climate talks there.

Hundreds of others were detained in a so called preventative action by police.

Security has been tight along the four-mile (6km) route, with extra police on the streets and security fences put up around some buildings.

Marches were also held in Australia, Hong Kong, Jakarta and the Philippines.

Danish police said they had rounded up more than 300 people in a preventive action against a section of the demonstration, AP news agency reported.

Television pictures showed scores of people handcuffed on the ground and surrounded by riot police
