Two days after bomb attacks at Brussels airport and on a packed metro killed 31 people and injured hundreds, a security guard who worked at a Belgian nuclear plant was murdered and his pass was stolen, Reuters cited Belgian media as reporting on Saturday. The French language Derniere Heure (DH) newspaper reported the security guard's badge was de-activated as soon as it was discovered he had been shot dead in the Charleroi region of Belgium and his badge stolen. A police spokeswoman said she could not comment because an investigation was ongoing.
