U.S. officials stepped up security in Washington, D.C. after the Islamic State militant group released a new video on Monday, warning that it will continue to target other countries, including the U.S., in planned terror attacks.

Just three days after killing over 100 people in Paris, France, members of the notorious terror organization, which is also known as ISIL or ISIS, made threats against Washington, D.C. and other European nations that have launched air strikes against Syria in a video that appeared on ISIS propaganda websites.

Although the authenticity of the video has not been independently verified, law enforcement increased security presence on Capitol Hill. An unnamed official with the U.S. Department of Homeland Security also made a statement in response to the video.

"While we take all threats seriously, we do not have specific credible information of an attack on the U.S. homeland," the official said.

The video starts with footage of news coverage of the Paris attacks, which killed at least 129 people in six different locations across the city on Friday. It then jumps to a man dressed in fatigues and a turban identified as Al Ghareeb the Algerian warning countries about a "crusader campaign."

"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 says, reports The New York Daily News.

He also warns of more attacks in Europe moving forward.

"I say to the European countries that we are coming, coming with booby traps and explosives, coming with explosive belts and (gun) silencers and you will be unable to stop us because today we are much stronger than before," he said, reports Reuters.

At another point in the video, a man identified as Al Karrar the Iraqi tells French President Francois Hollande, "We have decided to negotiate with you in the trenches and not in the hotels," a reference to international talks to end the Syrian war.
