Authorities evacuated a busy terminal at Brussels' Zaventem International Airport after a man refused to pass through a metal detector, and fled the scene. All flights from the terminal were immediately suspended and passengers were told to leave the terminal while police searched for the man. "This is a very exceptional situation," airport spokesman Jan Van Der Cruysse told VRT network. He said the suspect fled into the terminal to escape a security check. No further information about the suspect was available.
