ISIS get weapons and bombs with money, He's sell petrol, rob banks, and a lot of bad things. Please don't put conspiracy about this, get information before you talking some thing. ISIS kill by religion, in Alcoran has verses telling things like:
Sura 4:91 - "capture them and kill them wherever you do you suppose, because of this grant you absolute authority."
Sura 40:25 - "Kill the sons of those who, with him, believe, and let life with their wives! However, the conspiracy of the unprofitable unbelievers."
We need a armed population, all countries together to put a end in this, army in places dominated by ISIS and courage.
France, my condolences, I'm very frustrated about this, I living in country with a lot violence, but even so I going to ground when I saw the news. We will get this terrorist's, he's passed all limits, we can't accept this anymore. Never lower you head. Peace, Love and Bravery.
