A High Court prosecution of 15 members of an Islamic State recruiting group in Madrid revealed that it was headed by former Guantanamo detainee Lahcen Ikassrien, who used Madrid’s largest mosque as a recruitment center. The group, which called itself the Al Andalus Brigade, also operated a jihadist training camp on property it owned in Ávila. A High Court investigation last month disclosed that a Ceuta-based recruiting network headed by Yassin Ahmed Laarbi had sent 14 fighters to the Al Nusrah Front and the Islamic State in Syria; the network had also planned attacks in Spain.
