French police reported Sunday that Mehdi Nemmouche, who fought with jihadis in Syria in 2013, was arrested in Marseilles. He was carrying an AK-47 and pistol of the same type as used in the attack that killed four people, including a couple from Tel Aviv, at the Brussels Jewish Museum on May 24. He is being held on suspicion of murder and attempted murder for the terror attack in Brussels, AFP quoted a judicial source as saying.
