OSLO, May 13 (Xinhua) -- The Norwegian Police Security Service (PST) said ten more Norwegian foreign warriors had been probably killed in Syria and Iraq, with only 20 Norwegian warriors still alive in these countries, public broadcaster NRK reported Monday.
Up to now, the PST's estimate was that about 30 foreign warriors with Norwegian affiliation had survived the civil war in Syria. Many of these, however, have not given life signs for a long time, the report said.
"We have regularly adjusted the figures, but it is important to emphasize that the figures are not exactly accurate. It is difficult to confirm the information that comes from these areas," said Martin Bernsen, senior counsel at the PST.
Since the civil war in Syria broke out in 2011, around 100 people affiliated with Norway have traveled to Syria to join extremist groups.
According to the new figures from the PST, 60 of these are Norwegian citizens, while others are related to Norway in other ways, such as family and work relations.
The PST estimates that 40 of them have been killed, 40 have returned to Norway or gone to another country, and 20 are still alive.
Bernsen said 13 Norwegian foreign warriors are wanted in Syria and Iraq.
