OSLO, April 4 (Xinhua) -- Recent statistics from the Norwegian Police Security Service (PST) showed that more Norwegian foreign warriors got killed in Syria or Iraq, online newspaper Nettavisen reported Wednesday.
"Out of the 100 men and women who have gone to Syria and Iraq, we expect 30 to be killed, 40 have returned to Norway and 30 are still in Syria or in Iraq, but many of the remaining have an unclear status. Several of them may also be killed," Martin Bernsen, senior adviser in PST, told Nettavisen.
Earlier estimates from PST were around 20 killed foreign warriors, Bernsen said.
He also added three main reasons for small number of soldiers returning to Norway.
"One is that it is very difficult to get out of the conflict area. The second is that in Norway they will be arrested and risk long prison sentences, and the third reason is that many have died," Bernsen said.
Several female foreign warriors have given birth to children in Syria and Iraq, PST reported, and according to Bernsen, these children most likely still live in these countries.
"There are about ten women who have left Norway to join the caliphate. We have previously found that ten children with connection to Norway were born there. That figure is probably higher now," he said.
If people who have stayed in Syria or Iraq return to Norway to resume contact with extreme Islamists in this country, this could adversely affect the threat, according to PST's latest threat assessment for this year.
