Police are looking for eight men who drove onto the tarmac of Brussels international airport and robbed millions of dollars worth of diamonds from the hold of a Swiss-bound plane.

Brussels prosecutor's spokeswoman Anja Bijnens said Tuesday the armed and masked men crashed through the security perimeter fence around the airport with two cars and within minutes made their way to the plane, took the cache of stones and drove off into the darkness.

Police found a burnt-out van close to the airport later Monday night but said it was still looking for clues.
