Canada's counter-terrorist security force is investigating the third bomb attack in three weeks targeting natural gas pipelines owned by EnCana Corp. in western Canada, AP reported. EnCana spokeswoman Rhona DelFrari says the company has a crew at the scene trying to cap the gas leaking after Friday's blast near Dawson Creek, British Columbia. She said Saturday the leak is small, and there is no dangerous hydrogen sulfide leaking from the damaged area. The first blast on Oct. 11 was beside a gas line located about 50 kilometers (30 miles) east of Dawson Creek. The second occurred five days later close to the Alberta border.
