The manhunt for the suspected ringleader of a terror cell in Belgium has gone cold, a senior Belgian counterterrorism official told CNN.
Abdelhamid Abaaoud, a Belgian-Moroccan ISIS fighter, is believed to have been the head of the terror cell that was in a deadly shootout with police during a January 15 raid in the Belgian town of Verviers.
