Americans in ISIS Have Returned to U.S.

Americans who have fought for ISIS have returned to the United States, a senior Obama administration official said Monday. It marks the first time the U.S. government has acknowledged ISIS is here, though the number of Americans who have gone to fight has been disputed. According to the National Counterterrorism Center, more than 100 Americans have left to fight alongside ISIS or the al Qaeda-affiliated al-Nusra Front. Now it’s clear that some of them have come back to the States. “It includes those who’ve gone, those who’ve tried to go, some who’ve come back and are under active—the FBI is looking at them,” the official said. He would not state what is being done to monitor and prevent Americans who are fighting for ISIS from returning home. “This is worked on a case-by-case basis,” the official said, “I defer to the FBI.”
