Thousands of protesters have marched through Copenhagen to demand action from negotiators at the UN climate talks taking place in the city.
Many marchers were in costume to highlight the threats that climate change poses for the planet.
There was a carnival atmosphere, although police were on high alert for any signs of trouble.
Trouble came in the shape of black-clad protesters who threw bricks and released fireworks at police.
Elsewhere in the city, police rounded up hundreds of marchers in a preventative action.
As part of a global day of climate protest, activists also took to the streets in cities across Australia, as the country held its fifth Walk Against Warming.
Activists also marched through Bordeaux, south-west France, to show solidarity with other campaigners around the world.
In Johannesburg, South Africa, activists held a mock funeral for Planet Earth as they joined their voice to calls for strong action in Copenhagen to curb global warming.
Demonstrators in Manila, in the Philippines, added their painted palm prints to a wall in a show of solidarity with the global climate protests.
About 20 Chinese traditional drummers wearing T-shirts with climate change slogans took part in an event in Beijing.
