Police arrest pipeline protesters
Police have arrested hundreds of people who strapped themselves to the White House fence to protest at the proposed Keystone XL oil pipeline.
The protesters were mostly college students who participated in a peaceful march that began at Georgetown University and ended outside the White House.
They chanted "Climate justice now" and carried signs such as "Don't tarnish the Earth" in their efforts to convince President Barack Obama to reject the proposed Canada-to-Texas pipeline, which they say will contribute to global warming.
Police were waiting for them with buses and vans and protesters cheered as US Park Police warned them that blocking the pavement or strapping themselves to the fence would lead to their arrest. A total of 372 were arrested, police said.
