Islamic State has released a video appearing to show the militants who later carried out the Paris attacks beheading or shooting prisoners and training with weapons.
The 17-minute video claims to include the last statements of nine of the jihadis who took part in the 13 November attacks that killed 130 people.
"These are the last messages of the nine lions of the caliphate who were mobilised from their lairs to make a whole country, France, get down on its knees," a narrator in the video says.
It was uploaded to the group's online channel and shows some of the militants wearing camouflage clothes in a desert location.
One of them appears to be Bilal Hadfi, who became known as the "baby-faced terrorist".
He blew himself up outside the Stade de France during the Paris attacks.
"You destroy our homes and kill our fathers, our brothers, our sisters, our mothers, our children," he says.
Samy Amimour, who was raised in a Paris suburb near the French national stadium, says "soon on the Champs-Elysees" as he holds up a captive's head.
Salah Abdeslam, who fled Paris on the night of the attacks and remains at large, is not in the footage, but his brother Brahim, who blew himself up at a cafe, is shown at a makeshift shooting range.
The video also appears to show Abu Qital al Faransi - the gunman blew himself up after he opened fire in the Bataclan theatre.
The attackers are all identified in the video by noms de guerre, referring to their nationalities: three French, four Belgian and two Iraqis, referred to as Ali al Iraqi and Ukashah al Iraqi.
The militants speak French and Arabic and threaten "coalition" countries, including Britain.
The video includes a picture of British Prime Minister David Cameron accompanied by the words in English: "Whoever stands in the ranks of kufr (unbelievers) will be a target for our swords."
A spokeswoman for Mr Cameron said the new video was being examined.
"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," she said.
The video has not been independently verified and the French Foreign Ministry has declined to comment on it.
President Francois Hollande, however, said: "No threat will give France pause in what it must do against terrorist. And if I have taken steps to extend the state of emergency, it is because I am aware of the threat and that we will not concede."
It is not immediately clear where it was filmed, but the Raqqa Is Being Slaughtered Silently activist group has said at least three of the attackers were trained in the IS-controlled city in Syria.
