Greek police sources told AFP the 28-year-old man was arrested in Thessaloniki on the basis of an international warrant issued in 2017 by Rabat, and that a decision would be taken on his possible extradition to Morocco. Morocco’s MAP news agency, quoting a security source, said he was detained on Tuesday for alleged involvement in the planning of “terrorist” actions in Morocco. The suspect, known as Abu Mohamed Al-Fateh, had joined the extremist group in Syria in 2014 and held “positions of responsibility,” it said. He had appeared in a video showing the body of a Syrian fighter being mutilated. About 1,600 Moroccans joined extremist groups in Syria, Iraq and Libya, of whom 137 were killed, according to official figures in Morocco.
