In a series of coordinated actions on Monday, hundreds of activists affiliated with Tar Sands Blockade took over offices of companies associated with the construction of the Keystone XL pipeline.

From Common Dreams:

Members and supporters of the group Tar Sands Blockade staged public actions in Texas, Massachusetts, Maine and elsewhere on Monday in a series of independent protests at offices of the Transcanada Corporation—which is building the Keystone XL pipeline—and financial institutions supportive of tar sands infrastructure projects, such as TD Bank.

Campaigners in Westborough, Massachusetts—reportedly students—occupied the inside of the entryway at the company’s offices and refused to leave.
