The Dijla branch of the Islamic State of Iraq and Syria (ISIS) released a new video depicting unidentified jihadists celebrating the recent attacks on Paris and vowing the attacks would "conclude with the so-called White House."
In the video - titled "Paris Before Rome" -- militants warn French President Francois Hollande, U.S. President Barack Obama "and those who follow in his footsteps" to expect more strikes.
"We shall burn you with our suicide belts and our car bombs. We shall track you down wherever you go," a militant proclaims.
The jihadists warn that the attacks on France would expand to Washington, D.C.
"We began with you, and we shall conclude with the so-called White House. We shall turn it even blacker than our fire by the will of Allah," a militants says in the video. "Better still ... we shall blow it up just like we blew up the idols on this good land."
The video surfaced one day after another ISIS video that makes reference to Times Square. In what appeared to be a threat directed at the U.S., Times Square was shown along with New York City taxis and several Midtown locations, interspersed with what appeared to be a man preparing an explosive device and strapping it to himself.
However, New York Police Commissioner Bill Bratton downplayed the significance of the video.
"Been there, done that," Bratton said on "CBS This Morning" Thursday. "It appears to be a very hastily produced document that contains previously viewed video," which Bratton said includes footage from past threats directed at other countries. "So it didn't really change our stance at all."
Meanwhile, the U.S. State Department is warning that St. Peter's Basilica in Rome, Milan's cathedral and La Scala opera house, as well as "general venues" like churches, synagogues, restaurants, theaters and hotels have been identified as "potential targets" in those two cities for terrorist attacks.
The U.S. Embassy in Rome sent out early Thursday a "security message for U.S. citizens," saying that "terrorist groups may possibly utilize similar methods used in the recent Paris attack."
