DAESH terror organisation on Sunday published a video that purportedly shows footage of nine of the suspected Paris gunmen who killed 130 people on Nov 13, 2015.
Speaking in French and in Arabic, they also threatened the US-led coalition members and announced their "message is addressed to all the countries taking part in the (US-led) coalition" in Syria and Iraq since September 2014.
The video published on DAESH websites entitled "Kill wherever you find them", and shows four Belgians, three French citizens and two Iraqis who allegedly carried out the attacks.
It also shows the nine carrying out savage acts before the assault in Paris, including beheading and shooting people defined as hostages.
The video also shows a picture of the UK Prime Minister David Cameron accompanied by the sentence in English: "Whoever stands in the ranks of kufr (unbelievers) will be a target for our swords."
Cameron's spokeswoman told reporters on Monday, "We are in the process of examining this latest propaganda video which is another move from an appalling terrorist group that's clearly in decline and in retreat."
British fighter jets launched their first air strikes against DAESH in war torn Syria in December 2015.
The video also defines the attackers as "lions" who "brought France to its knees."
It was not clear why DAESH published the video more than two months after the Paris attacks.
Seven DAESH members died during the attacks and two during police operations.
The multiple attacks in Paris on November 13 killed 130 people and wounded hundreds of others, the attacks have been described by President Francois Hollande as an "act of war" carried out by DAESH.
Gunmen and suicide bombers hit a concert hall, restaurants and bars and the Stade de France stadium where France's football team was playing a football match against Germany.
France has been hitting DAESH targets in Iraq since last year and conducted its first air strikes against DAESH in Syria in late September as part of an ongoing US-led operation against the terrorist organisation that currently controls large swathes of Iraq and Syria.
