MOSCOW (Sputnik) — According to the document from the Federal Bureau of Investigation, Department of Homeland Security and National Counterterrorism Center, the "reach and popularity" of social media networks made it easier for US-based extremists to get in touch with organizations abroad, which could "potentially direct" them. The Islamic State’s use of media is "unprecedented," the report said.
The bulletin also stated that there is a heightened threat of ISIL attacks during holidays and military events. There is no "credible threat" right now, but the US agencies are "aware of recent information suggesting US military bases, locations, and events could be targeted in the near-term."
"The large number of social media postings by US-based ISIL [Islamic State] supporters is challenging for investigators in differentiating those supporters focused only on promoting pro-ISIL rhetoric, which may be protected speech, vice [versus] detecting those prepared to engage in violence on the group's behalf," the bulletin said.
Known to target potential members through media including Twitter, Facebook, YouTube, Instagram and Tumblr, the Islamic State militants have attracted thousands of young foreign supporters.
According to the US National Counterterrorism Center, at least 20,000 foreign fighters have joined the ISIL.
