FORT MCMURRAY, Alta. - Greenpeace members are continuing their protest at a Shell oilsands project in northern Alberta, but the company says the mine is operating at full production.

About 24 Greenpeace members from Canada, the United States and France chained themselves to giant earth-moving equipment Tuesday and placed giant banners on the ground reading, Tarsands: Climate Crime."

John Abbott, Shell's vice-president of heavy oil, says Shell has taken a non-confrontational approach to this protest but will always act to ensure the safety of people and its operations.

He says the company has launched an investigation into the protest at the Albian Sands project and is beefing up security.

Abbott says Shell is developing an important resource that society needs and is doing it safely, responsibly and in compliance with all laws and regulations.

Greenpeace says Canadian oilsands oil undermines North America's clean energy future.
