Climate change protest at Heathrow

Hundreds of climate demonstrators set up a tent camp next to London's Heathrow airport on Monday and threatened "direct action" at the world's busiest air hub to protest against global warming. Police with batons were on alert at the field where the camp is based, within one kilometer of the airport complex. The campaigners plan a week of activities they say will culminate on Sunday in 24 hours of "direct action" in a bid to force the government to halt the planned expansion of the airport, which they argue will exacerbate climate change.
