The French fighters are identified as Abu Osama al-Faranci, Abu Maryam al-Faranci and Abu Salman al-Faranci. Abu Maryam al-Faranci says the “mujahideen” will not hesitate to chop the heads of the “enemies of Islam.” “You will even fear travelling to the market,” he said. Abu Salman al-Faranci is featured the most in the video.

Abu Maryam al-Faranci's real name is Kevin Chassan. He is from Toulouse and was killed in a suicide bombing in Iraq in May, 2015.

In February, 2015, ISIS released "Message to France" featuring two Belgian fighters.

The man at the left was identified as Lotfi Aoumeur (kunya unknown), aged 24 from Verviers, Belgium. He served two years in a medical unit of the Belgian army (2010-2012). The Department of Defence acknowledged this information officialy.
At the right: Redwane Hajaoui (aka Abu Khalid al-Maghribi), aged 22 from Verviers, Belgium. He left for Syria early 2014.

Here is part of their message:

This is a message to you François Hollande, a message to everyone living in France. Know that the soldiers of the Islamic State are everywhere and that the nightmare has just begun. You have crossed a line by insulting our prophet and religion. We all await the order of our caliph, Abu Bakr al-Baghdadi, to bomb you, kill you, behead you. The nightmare has just begun. We will have no pity for you.

This is a message for all French speaking Muslims, for everybody who speaks French. You will have to make a choice here; this is a battle between Muslims and kufr, a battle between true and wrong. It is time to pick a side, whether you’re with us, whether with them. Those who didn’t make Hijra yet, should do so, it is an obligation. But if one can not leave, act from within. Fight them, kill them, with whatever weapon available. Smash them down, burn their cars, burn down police stations. Make Hijra

So we are ready to fight you, we are waiting. You are just a coward bombing us. But you, François Hollande, and your little men, will never come, because you are nothing but a coward. You are worthless. Why are you afraid to fight us here on the ground? Come to this ground and fight us here. Come taste this. But for now my knive is thirsty for blood, so I kill murtadeen, …, all who attack us we fight back.

We are fighting here now and will be forgiving towards the Muslims and harsh for the disbelievers. But we will come with this and cut off your heads. Car bombs from Paris to Brussels are no problem.

A third French ISIS fighter video calling for attacks in France was released in late December or early January, 2015. (I saved it on my computer in December but the media says it was released in January.) It's called "Recevez Ce Message", and contains a screed against nationalism. I mentioned it other anti-French videos at the time here and here.

In early February, 2015, ISIS released "Blow Up France 2" which included the girlfriend of Almedy Coulibaly.

None of these are new videos. All were mentioned and described in mainstream media when published.
