The Islamic State group has now threatened to attack Washington. As Paris reels from the deadly carnage of Friday attacks, Islamic State has released a new video on Monday, warning that countries conducting airstrikes against Syria would face similar attacks as France.

The video, which was distributed on a social networking site run by the Islamic State, started off with clippings from the aftermath of the attacks and featured French President Francois Hollande condemning them.

According to the Washington Post, the 11-minute long video was claimed to be made a group named “ Wilayat Kirkuk, ” hailing from Salahuddin province in the northern part of Iraq. However, the video’s authenticity could not be confirmed.

A man named Al Ghareeb the Algerian was identified from the video subtitles who said that countries that take part in the “crusader campaign” against Syria would witness a day similar to Paris. “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 as interpreted by Reuters.

The video was released just after France launched airstrikes (in coordination with the U.S.) in ISIS targets in Syrian city of Raqqa. The French government has vowed to retaliate mercilessly following the attack in its capital city.

The man who appeared in the video also warned Europe of future potential attacks. "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 as quoted by Reuters.

Another man who also appeared in the video and identified as Al Karrar the Iraqi said that they would be negotiating with the Hollande in the trenches and not inside hotels, referring to the Syrian peace talks in Vienna.

On Friday, Nov. 13, around 9:30 p.m. local time (Sat morning AEDT), gunmen and suicide bombers attacked more than 150 people across Paris. The death toll has crossed the 120 mark. The attacks have been declared as the deadliest the city has seen since the 50s.
