In the latest protest against the Keystone XL oil pipeline, 25 people were arrested after handcuffing themselves together inside a TransCanada office in Westborough, Massachusetts. More than 100 students, mothers and clergy members staged a “funeral for our future,” saying TransCanada’s pipeline would spur devastating climate change, pollution and potential spills.

Protesters: [singing] “They are digging us a hole. They are digging us a hole, six feet underground, where the pipeline will go.”

The Keystone XL pipeline would carry tar sands crude from Canada to Texas. A decision from President Obama on the project is expected soon, after a State Department review found it does not pose a serious threat to the environment.
