A former Guantanamo Bay prisoner was reportedly among four individuals arrested Tuesday by authorities in Spain and Morocco for alleged ties to terror group ISIS.

The Associated Press reported:

“Three people were arrested in Spain’s North African enclave city of Ceuta while a Moroccan was arrested in the Moroccan border town of Farkhana, next to Melilla, Spain’s other North African enclave, statements from the two nations’ interior ministries said. One of those detained in Ceuta was the former Guantanamo detainee who was not named by Spanish authorities but described as “a leader who was trained in handling weapons, explosives, and in military tactics.” After being captured in 2002 and held in Guantanamo, he was returned to Spain in 2004, said Interior Minister Jorge Fernandez Diaz.”
