A lone attacker who killed one police officer and hurt another in a Brussels stabbing was on a list of potential extremists, officials said.
The suspect, born in 1990 and named as Yassine M, went to a police station early on Thursday to express his hatred for officers but could not be arrested before he launched his attack on two officers that evening.
