A new Islamic State video has warned that countries taking part in Syria airstrikes will suffer the same fate as France, which was hit with multiple attacks on Friday. It specifically threatens an attack on Washington.

LIVE UPDATES on Paris attacks: Investigation widens as world mourns victims 

A man in the video states that just as the center of France was hit by terror attacks on Friday, the US capital of Washington DC will suffer the same outcome at the hands of Islamic State (IS, formerly ISIS/ISIL).

It was not immediately possible to verify the authenticity of the video, Reuters reported.

ISIS claimed responsibility for attacks in Paris on Friday which left 129 people dead and 352 others wounded. Seven of the attackers blew themselves up, and police have been searching intensively for accomplices.

The assaults were the worst to take place on French soil since World War II.

Speaking at the Center for Strategic & International Studies on Monday, CIA director John Brennan said he wouldn't consider the Paris attacks a “one-off event,” but added that he would never say attacks are “inevitable," as the agency "works 24/7 to prevent attacks from taking place." 

ISIS also claimed it brought down a Russian airplane over Egypt's Sinai Peninsula last month, killing all 224 passengers onboard.

Moscow has not confirmed the militant group's role in the crash, and an investigation is ongoing. Both Russia and Egypt previously stated that ISIS does not have the means to shoot down a plane.
