at large? >> reporter: it is still very much an active manhunt, an international manhunt to be precise, and there is a lot of stepped up activity here across brussels. today as you mentioned there was two sets of raids, a total of nine searches and raids across districts of brussels. the first six raids happened overnight in the early hours of the morning, targeted one of the attackers who was involved in blowing himself up at the stade de france on last friday night. now, that raid actually, believe it or not, was scheduled to take place -- or those raids were scheduled to take place, part of the investigation into bilal hadfi, several months ago. this is something that's been in the works. and it was only accelerated after last friday's attacks. and certainly a lot of folks are going to have questions as to whether or not there was a lack of moving quickly, if you will, by belgian security forces that could have prevented this individual from participating.
