CALGARY - Twenty imams from across the country have issued an edict condemning extremists and terrorists who would launch an attack on the United States or Canada.

The fatwa, or religious guideline, says that Muslims must stand up against such "evil" attacks.

It says that it's up to religious leaders in the country to show others around the world that Muslims in Canada and the U.S. "have complete freedom to practice Islam."

It notes that the freedom to practice Islam in North America is often greater than in many Muslim countries.

The fatwa concludes that Muslims in these countries must therefore expose any person who plans harm to fellow Canadians or Americans.
