Italian police have arrested a Moroccan man on suspicion he helped organize and execute the March 18th attack on Tunisia's Bardo Museum that left 22 people dead.
Abdelmajid Touil was arrested in Gaggiano, near Milan.
The only trace that Italian authorities had of Touil prior to his arrest was that he had arrived in Italy on Feb. 17 along with migrants from a smuggler's boat, police said. He was identified by authorities in Porto Empedocle, Sicily, and was subsequently issued an expulsion decree, Megale said.
Anti-immigrant politicians have warned that Islamic extremists might enter Italy via any one of the dozens of migrant boats setting off weekly from Libya for European shores. Confirmation that Abdelmajid had made at least one trip to Italy by boat has fueled criticism of the massive, Italy-led Mediterranean operation to rescue would-be refugees crossing the Mediterranean.
