ISIS Urges Killing of Citizens From US-Led Coalition

A 42-minute audio recording by an ISIS spokesman was released on social media Sunday, in which the group calls on Muslims to kill civilians in countries that belong to the anti-ISIS, U.S.-led coalition.

"If you can kill a disbelieving American or European, especially the spiteful and filthy French, or an Australian, or a Canadian or any other disbeliever, then rely upon Allah, and kill him in any manner or way however it may be," an ISIS spokesman says.

This latest threat comes as the Islamic State group posts new pictures of some of its British recruits, and President Obama heads to the UN to seek an international effort to stop such ISIS fighters from traveling unimpeded to spread their war of terror.

But U.S. Ambassador to the United Nations Samantha Power Sunday told George Stephanopoulos on "This Week," stopping the threat from ISIS and its fighters won't happen anytime soon.

"We think again the strategy can succeed, and most importantly that we have the greatest military in the world, they believe that," Power said. "I think the president has said it will be over several years."

U.S. and British authorities this morning are also bracing for word on the fate of ISIS hostage Alan Henning.

The White House declined to comment on the new recording today.

Over the weekend there were new pleas for mercy from his wife and from leaders of the Muslim community, even al Qaeda, that he be spared because the one time British taxi driver only went to Syria as a driver for an Islamic relief mission.
