America: FBI issue public appeal to track IS militants

The FBI have issued a public appeal to help track fighters with the Islamic State

“We need the public's assistance in identifying US persons going to fight overseas with terrorist groups or who are returning home from fighting overseas,” said Michael Steinbach, assistant director of the FBI’s Counterterrorism Division.

“No piece of information is too small.”

Boston FBI special agent Vincent Lisi said to CBS last night that “traditionally, the FBI would use other techniques to try to determine who the person was,”

“We’ve come up empty there now so we need to reach out to the public.”
