The Federal Bureau of Investigation is offering up to $5 million for information leading to the arrest of a U.S. citizen on the “Most Wanted Terrorist” list.

The FBI’s Rewards For Justice Program, along with the U.S. Department of State, is offering the reward to seek out Jehad Serwan Mostafa, 37.

Mostafa is believed to be the highest-ranking U.S. citizen fighting with al-Shabaab, a Somalia-based terrorist organization, the FBI said.

It is believed that Mostafa joined al-Shabaab in approximately 2006 and has served in many capacities, including serving as a military instructor at the terrorist organization’s training camps, a leader of the foreign fighters, a leader and propagandist in the terrorist organization’s media wing, an intermediary between al-Shabaab and other terrorist organizations and as a leader in the group’s use of explosives in terrorist attacks.
