COPENHAGEN, Denmark, Dec. 12 (UPI) -- Thousands of marchers swarmed central Copenhagen Saturday, urging action on global warming, and police and radicals clashed in elsewhere in the Danish city.
A crowd estimated at 60,000 to 100,000 people from around the world participated in the main demonstration, The New York Times reported. They walked from Christiansborg Slotsplads or Castle Square toward the Bella Center, the convention hall where delegates from nearly 200 countries are gathered to forge an agreement to reduce greenhouse gas emissions.
Marchers carried flags and banners demanding action from world leaders to stop global warming. One read "Bla, Bla, Bla. Act Now!"
"My words cannot replace action," Helle Thorning-Schmidt, the leader of the Danish Social Democratic Party. "We are here to show leaders that what is made by man, can be changed by man."
A police spokeswoman said there was scattered violence, with radical protesters breaking windows, throwing rocks and setting at least four cars on fire. At least one officer was struck in the face by a rock and police made about 950 arrests, the Times reported.
"We saved the demonstration from being disturbed totally," Per Larsen, chief coordinator for the Danish police, said. "There were some hard-core protesters that we have neutralized."
