The head of the PST said the agency tried over three years ago to dissuade Westgate Mall terror suspect Hassan Abdi Dhuhulow from becoming a jihadist. The PST estimates that 30-40 people have traveled from Norway to fight in Syria but says the actual number may be higher. The father of two teenage Norwegian girls who recently left for Syria said the elder girl called from the Turkish border town of Hatay and said she is willing to die as a jihadist in Syria.
