ReutersStills of the video, seen by the Site monitoring group, show nine men resembling the suspects.A video apparently showing some of the suspected Paris attackers in the Middle East has been posted online, a group monitoring jihadist activity says.
It also names locations that were attacked on 13 November, leaving 130 people dead.
The video was released through the media channel of the so-called Islamic State (IS).
A Site analyst says four of the attackers are seen beheading and shooting prisoners.
It said the video was filmed in Raqqa, the de facto capital of IS, before the Paris attacks.
One of the images shows a man closely resembling Abdelhamid Abaaoud, the suspected ringleader of the attacks.
Abaaoud, a Belgian national, died in a police raid on a flat in Saint-Denis, near Paris, days after the attacks.
Nine suspected attackers died on 13 November or in the days after, and two more are on the run.
France's foreign ministry has declined to comment on the video.
