More than 100 climate activists were detained Wednesday for trying to break into a UN conference where 193 nations are deadlocked in talks on a deal to curb global warming, police said.
Protesters said they wanted to take over the global conference and turn it into a "people's assembly."
Police spokesman Johnny Lundberg said the activists were arrested for attempting to pass through the security perimeter set up around the suburban conference center. There were no reports of injuries.
A separate group of activists from Friends of the Earth staged a sit-in protest outside the security area because they were not being allowed into the conference even though they were accredited.
A working group dealing with core issues at the conference debated until just before dawn without setting new goals for reducing greenhouse gas emissions or for financing poorer countries' efforts to cope with rising seas, drought and other results of global warming.
