Manhunt underway for Brussels Airport Bombing suspect and Terrorist Cells

Belgium -- Terror in Brussels, a manhunt is under way for a suspect in Tuesday's deadly blasts in Brussels. Belgian police say they are searching for a man seen in surveillance footage pushing an airport baggage trolley alongside a pair of suicide bombers. U.S. officials believe more terrorists linked to the attacks are still at large and likely plotting more strikes. Earlier, authorities had identified the man as Najim Laachraoui, 25, who is also wanted in connection with last year's attacks in Paris. The tragedy has triggered security alerts across western Europe and brought warnings from American officials. The State Department issued an alert to all U.S. citizens traveling in Europe, warning of "near-term" attacks there. More than 30 people were killed and over 200 others injured in the bombing attacks at Brussels Airport and a rush-hour metro train in the Belgian capital. ISIS has claimed responsibility.
