Mohamed Abdeslam is the brother of two of the terrorists that attacked Paris Friday night. They hail from Molenbeek, an impoverished immigrant district in Brussels known to be a jihadi hotbed. One of Mohamed's brothers, Ibrahim, blew himself up outside of the cafe Comptoir Voltaire near the Bataclan concert hall. The other, Salah, is now on the run after making it back across the Belgian border and is currently one of the world's most wanted terrorists. Mohamed was held and questioned by French police, but later released after it was determined he played no role in the attacks.
