The Islamic State group issued a new 12-minute video Monday, November 16, threatening to attack all nations involved in bombing IS positions in Syria and Iraq.

One man in the video threatened to target the United States in the same style as Paris, saying that as “we struck France on its ground in Paris, we will strike America on its ground in Washington.”

This comes even as France identified a 27-year-old Belgian who once boasted about killing “infidels” and fought for the Islamic State group in Syria as the mastermind of the Paris attacks, and President Francois Hollande vowed Monday to forge a united coalition capable of defeating the jihadists at home and abroad.

The video, linked here from the Reuters site, appeared on a website used by Islamic State to post its messages, begins with news footage of the aftermath of Friday’s Paris shootings in which at least 129 people were killed.

The message to countries involved in what it called the “crusader campaign” was delivered by a man dressed in fatigues and a turban, and identified in subtitles as Al Ghareeb the Algerian.

“We say to the states that take part in the crusader campaign that, by God, you will have a day, God willing, like France’s and by God, as we struck France in the center of its abode in Paris, then we swear that we will strike America at its center in Washington,” the man said.

It was not immediately possible to verify the authenticity of the video, which purports to be the work of Islamic State fighters in the Iraqi province of Salahuddine, north of Baghdad.

The U.S. Department of Homeland Security would not comment on the video but said it has not received information indicating a potential attack.

“While we take all threats seriously, we do not have specific credible information of an attack on the U.S. homeland,” a DHS official said on condition of anonymity to First Post.
