The FBI announced on Thursday the arrest of a Texas man who allegedly created and disseminated ISIS propaganda and wanted to commit a “9/11-style” attack in the United States.

Federal prosecutors say that a 28-year-old Houston resident created ISIS recruitment propaganda, researched how to build an explosive belt, and researched security measures for local Jewish sites.

A 28-year-old man in Houston, Anas Said, has been indicted and arrested on charges he attempted to provide material support to the Islamic State of Iraq and al-Sham (ISIS), a federally designated foreign terrorist organization (FTO).
