But not only is ISIS growing--it is getting more dangerous.
From Fox News:
There is growing evidence that ISIS is experimenting with chemical weapons as the number of foreign fighters hits a new high, according to current and former government officials.
Photos taken by the Kurds in northern Iraq last summer and fall and reviewed by Fox News show burns and blistering on the skin that a source on the ground there said are consistent with the use of chemical agents. The agents were described as "odorless, colorless and absorbed through the clothing," causing burns or illness hours later.
"I think it's, could be a perfect testing ground," former FBI intelligence officer Timothy Gil Sr. said. "They (ISIS) were particularly interested in using these chemicals in confined space environments, soft targets like shopping malls and movie theaters."
Gill who is doing his own independent research for an upcoming international conference on weapons of mass destruction said there is a disturbing trend, that ISIS is using safe havens in Syria, Iraq and potentially Libya as laboratories to learn how chemical agents impact the battlefield, with the goal of sharing their expertise via social media with ISIS followers outside the region.
