 ISIS has released propaganda videos celebrating the attacks in Paris and threatening to carry out another in Washington, D.C. 
  
 In one of the videos, a purported Algerian member of the terror group addresses the United States, saying, "like France we will strike in its center in Washington," according to global security firm and NBC News analyst Flashpoint Intelligence.

 The man also threatens that ISIS is coming to Europe with "booby traps and explosives." 
  
 Another of the videos includes fighters congratulating their "brothers" in France for perpetrating Friday night's massacre, and urging more violence, Flashpoint said. 
  
 A senior U.S. official told NBC News that the video had not yet been authenticated. 
  
 "It looks like a typical propaganda video, and it's getting attention now because ISIS has been in the news," the official said. ||||| CAIRO (Reuters) - Islamic State warned in a new video on Monday that countries taking part in air strikes against Syria would suffer the same fate as France, and threatened to attack in Washington. 
  
 The video, which 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. 
  
 The French government has called the Paris attacks an act of war and said it would not end its air strikes against Islamic State in Syria and Iraq. 
  
 French fighter jets launched their biggest raids in Syria to date on Sunday, targeting the Islamic State’s stronghold in the city of Raqqa, in coordination with U.S. forces. 
  
 Police raided homes of suspected Islamist militants across France overnight following the Paris attacks.

 “Al Ghareeb the Algerian” also warned Europe in the video that more attacks were coming. 
  
 “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. 
  
 Apparently referring to international talks to end the Syrian war, another man identified in the video 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.” |||||
Output:
The Paris terror attacks were just the start if airstrikes against Syria don't cease, according to unauthenticated ISIS video that surfaced Monday—and the next target could be DC, reports Reuters. The video—which the news agency says was posted on a site used by ISIS, supposedly by militants north of Baghdad—features a man dressed in fatigues and a turban and labeled in the subtitles as "Al Ghareeb the Algerian." "We say to the states that take part in the crusader campaign that … 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 in the clip. Europe gets an additional warning as well: "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." The idea of talks to end the Syrian war were also roundly dismissed in the video, with another man called "Al Karrar the Iraqi" addressing French President Francois Hollande: "We have decided to negotiate with you in the trenches and not in the hotels." A senior US official, however, tells NBC News that the video looks like many other ISIS propaganda videos and that it may just be bubbling to the surface because of Friday's attacks.
