Ocean's Fourteen may have just found its new plot line. On Monday evening eight masked and heavily armed men drove through a security fence at Brussels International Airport and demanded crew open the cargo doors to Swiss-bound plane. They withdrew 120 packets of diamonds--worth up to $350 million--and sped off, all in a matter of minutes. The robbers were reportedly disguised as airport police, with armbands on their uniforms and blue flashing lights on their cars. One car was found burned out nearby the airport."It was well-prepared and very professional," said Ms. Van Wymersch, a Belgian prosecutor.
