large area, police say, before he was captured. unfortunately four people, four women and one man lost their lives, there are also two injuries and you can imagine these horrific scenes again of arrows being blown over streets, seen in the sideway, it left a community in shock. police say they're now treating it as a terror investigation. they are hoping that that investigation will reveal the motivation of the attacker, but here is what we know about him so far. he's a 37-year-old danish national living in norway. he had been previously flagged by police for links to radicalization. we also understand he's a recent convert to islam. there is questions there for authorities. meanwhile, police have been given a very rare temporary order to carry firearms and there is hope that that could begin to calm tensions there. >> i'm sure they'll be asking if they have ties to international islamist groups. thanks so much. there are new details this morning on u.s. citizens who remain stranded in afghanistan.
