A French-born man raised in the Boston area who is already on the FBI Most Wanted Terrorists list is believed to be running the Islamic State’s social-media operations, according to several outlets.

Ahmad Abousamra, a 32-year-old raised in the suburb of Stoughton, is wanted for multiple efforts to aid in the killing of Americans, including by engaging in military training in Yemen and Pakistan and by providing material to al-Qaeda and other terrorist groups.

Abousamra attended Northeastern University and the University of Massachusetts–Boston, where he developed computer skills and eventually graduated from the latter with a degree in computer science. He is reportedly using his technological knowledge to target and recruit potential fighters, according to ABC News.

“If you do have a European language ability, if you have computer skills, if you are quite clever and you come join ISIS, you are likely to be used for social media output,” said Peter Neumann, the director of the International Centre for the Study of Radicalisation.

Abousamra first teamed up with Islamist terrorists when he joined al-Qaeda’s media operations in 2004 while in Iraq. He returned to the United States two years later, where he was questioned and released by the FBI’s Joint Terrorism Task Force, but he then returned to the Middle East, this time to Syria. The U.S. government has offered a $50,000 reward for tips leading to his arrest since 2009.
