Several dozen suspected terrorist bombmakers, including some believed to have targeted American troops, may have mistakenly been allowed to move to the United States as war refugees, according to FBI agents investigating the remnants of roadside bombs recovered from Iraq and Afghanistan.
The discovery in 2009 of two al Qaeda-Iraq terrorists living as refugees in Bowling Green, Kentucky -- who later admitted in court that they'd attacked U.S. soldiers in Iraq -- prompted the bureau to assign hundreds of specialists to an around-the-clock effort aimed at checking its archive of 100,000 improvised explosive devices collected in the war zones, known as IEDs, for other suspected terrorists' fingerprints.
"We are currently supporting dozens of current counter-terrorism investigations like that," FBI Agent Gregory Carl, director of the Terrorist Explosive Device Analytical Center (TEDAC), said in an ABC News interview to be broadcast tonight on ABC News' "World News with Diane Sawyer" and "Nightline".
"I wouldn't be surprised if there were many more than that," said House Committee on Homeland Security Chairman Michael McCaul. "And these are trained terrorists in the art of bombmaking that are inside the United States; and quite frankly, from a homeland security perspective, that really concerns me."
As a result of the Kentucky case, the State Department stopped processing Iraq refugees for six months in 2011, federal officials told ABC News – even for many who had heroically helped U.S. forces as interpreters and intelligence assets. One Iraqi who had aided American troops was assassinated before his refugee application could be processed, because of the immigration delays, two U.S. officials said. In 2011, fewer than 10,000 Iraqis were resettled as refugees in the U.S., half the number from the year before, State Department statistics show.
