U.S. Intelligence Identifies American-Born ISIL Fighters

American intelligence and law enforcement agencies have identified nearly a dozen Americans who have traveled to Syria to fight for the Islamic State in Iraq and Syria, the militant group that the Obama administration says poses the greatest threat to the United States since Al Qaeda before the Sept. 11, 2001, attacks.

As ISIS has seized large expanses of territory in recent months, it has drawn more foreign men to Syria, requiring more American and European law enforcement resources in the attempt to stop the flow of fighters, senior American officials said. And as a result of the increasing numbers of men, ISIS is now recruiting foreign women as jihadist wives.
