Just hours after two ISIS suicide bombers blew themselves up inside Brussels airport on the morning of March 22, 2016, Belgian police discovered their safe house/bomb factory, thanks to the testimony of the taxi driver who picked up the attackers and took them to the airport. In a trash can outside the residence on rue Max Roos in the Brussels district of Schaerbeek, Belgian police found a discarded laptop belonging to one of the suicide bombers — a Belgian named Najim Laachraoui — who is believed to have built the bombs used in the Paris and Brussels attacks.
