Five terrorists — three dead, two whose fates are unknown. So far, that’s how many people that authorities say played a part in Tuesday’s terror attacks in Brussels, Belgium, that killed 31 people and injured 270. Two were allegedly involved in bombing a train near the Maelbeek metro station. Of them, one has been identified as Khalid El Bakraoui, who died in that suicide attack. Authorities believe a second, unnamed person was also involved in that blast. That man’s whereabouts — and whether he’s dead or alive — is unknown.

He added that someone with good but less than popular ideas would have a hard time competing against someone with a “good smile.”
