“The recent events in Europe re-emphasize our need to remain vigilant in the homeland, as these small scale attacks are feasible within the United States,” Steinbach said in a statement on Wednesday.
Steinbach said that the FBI was concerned about the possibility of “homegrown extremists” becoming radicalized by information provided by terrorists available on the Internet.
Most recently, Radicalized Muslims organized several terrorist attacks throughout Paris in January. The gunmen attacked the Charlie Hebdo editorial office on January 7. The next day, another gunman, believed to be associated with the Islamic State extremist group, shot a police officer dead near the French capital. The following day the same gunman killed four hostages in a Paris kosher food shop.
Over 15,000 foreign fighters, including many citizens of the United States and European countries, have travelled to Syria to join extremist groups since 2011, according to a UN estimate.
