Environment News Service: Police arrested more than 370 young people who tied themselves to the White House fence on Sunday to protest the proposed Keystone XL tar sands oil pipeline.
Called XL Dissent, the protest was organized by college and university students to urge President Barack Obama to reject the northern leg of TransCanada`s proposed Keystone XL pipeline, which needs presidential approval because it would cross an international border on its way from the Alberta tar sands to refineries in Texas.
