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.
