MIAMI—Ongoing coordination between judicial and law enforcement authorities across Europe and the United States resulted in the dismantlement of critical online infrastructure of platforms and websites used for the Islamic State of Iraq and al-Sham’s (ISIS) propagation of terrorist content. Dozens of servers supporting ISIS’s online propaganda infrastructure were taken down earlier this week in the United States, Germany, the Netherlands, and Iceland.

Spanish authorities arrested nine individuals with alleged ties to the use of the disrupted servers.

The disrupted servers supported the I’lam Media Foundation, and other terrorist websites. I’lam Media Foundation, although not formally recognized in ISIS’s official platform catalog, serves as a primary conduit for both “official” content endorsed by ISIS and “unofficial” content created by sympathizers worldwide. I’lam Media Foundation’s online presence boasts a formidable multilingual capability, disseminating ISIS ideologies and directives in over 30 languages, including Spanish, Arabic, English, French, Urdu, and German, catering to a global audience.

This action resulted in the dismantlement of the largest ISIS online propaganda network and infrastructure globally. The operation was led by the FBI Miami Field Office and Spain’s Civil Guard Information Service, bolstered by the coordination efforts of Europol, Eurojust, and the governments of Netherlands, Germany, France, Estonia, Romania, and Iceland. Within the United States and in addition to the FBI’s Miami Field Office, the U.S. Attorney’s Office for the Southern District of Florida, and the Department of Justice National Security Division Counterterrorism Section provided crucial support for this operation.

The FBI, through its legal attachés, maintains close contact with our overseas law enforcement partners in accordance with executive orders, statutes, treaties, Attorney General Guidelines, FBI policies, and interagency agreements that help advance the FBI’s mission to prevent attacks against the citizens and interests of the United States.
