According to Syrian Democratic Forces (SDF), a number of jihadis involved in the killing of four Americans in Syria in January have been captured.

On January 16, a suicide bomber detonated in an urban restaurant in the Syrian city of Manbij, where the Americans were attending a meeting with local dignitaries. The blast killed Chief Warrant Officer 2nd Class Jonathan Farmer, a Special Forces operator assigned to the 5th Special Forces Group (Airborne); Chief Cryptologic Technician Shannon Kent, a U.S. Navy interpreter; former Navy SEAL and Defense Intelligence Agency (DIA) contractor Scott Wirtz; and Department of Defense (DOD) contractor Ghadir Taher.

Mustafa Bali, a representative of the SDF, said in a tweet, “A group of suspects believed to be involved [in the] January 16 Manbij bombing that killed several U.S. and SDF servicemen were captured following technical surveillance by our forces. The outcome of the ongoing investigation will be shared at a later time.”

It still remains unclear what role the captured ISIS fighters played in the Manbij attack or how the SDF forces were able to link them to the incident. There also isn’t any indication of what will happen to them if their involvement is proven. Since the onset of the Global War on Terrorism (GWOT), extraditing terrorists to the U.S. has been a tricky process, brimming with legal and political hurdles.
