So who is behind this attack? Did the three (or as some reports claim five) attackers act on their own? The attackers appear to have training and the attack seems to have been planned. Unlike suicide attacks, they fled the scene in a vehicle. The gunmen appear to be wearing tactical and bulletproof vests, and carrying AK assault rifles. Via Memlik Pasha:
They demonstrate good fire discipline, single or double-tap targets, conserve ammo, use hand signals, move calmly, methodically.
It sounds more like along the lines of a Mumbai attack than a lone wolf attack.
Was it ISIS? While its supporters undoubtedly approve, and it may be the brothers trained in Syria, I doubt it. It doesn't seem like their MO. It may have been AQAP and Yemen inspired.
One of the police officials said they were linked to a Yemeni terrorist network, and Cedric Le Bechec, a witness who encountered the escaping gunmen, quoted the attackers as saying: "You can tell the media that it's al-Qaida in Yemen."
The editor was reportedly on this AQAP hit list (third row, second down.)
What are ISIS supporters saying on Twitter? Mostly, that people should be know you can't insult the Prophet. I see a lot of comments like this one:
Why don't people learn from history? Insulting Prophet Muhammad is a line that MUST not be crossed.
Do the Charlie Hebdo cartoons go too far? Were they too provocative, even for satire? It doesn't matter. Killing for retribution and revenge is vigilante justice. It's wrong no matter who does it. It's not justice at all.
If you comment, please do not make negative comments about Islam, Muslims or the Prophet. Personal insults and attacks on anyone are not allowed here. These killings are not grounds for an exception.
