OTTAWA, Canada — Anti-fracking demonstrators set tires ablaze to block a New Brunswick highway Monday in a fiery response to a judge’s decision to extend an injunction limiting their protests against a Texas-based shale gas exploration company.

In a courtroom in Fredericton, the capital of New Brunswick, Judge Paulette Garnett ruled to continue through Dec. 17 the injunction obtained by SWN Resources Canada against a coalition of protesters led by Mi’kmaq indigenous people from the Elsipogtog First Nation.

The injunction, which SWN obtained on Nov. 22, is designed to keep protesters from interfering with SWN’s seismic testing work. It requires that demonstrators remain at least 250 yards in front of or behind contractors and their vehicles and 20 yards to the side.

The Mi’kmaq have argued that SWN is conducting exploration work on land that they never ceded to the crown when they signed treaties with the British in the 18th century. http://america.aljazeera.com/articles/2013/12/2/canada-anti-frackingprotestersanswerinjunctionextensionwithblock.html
