Around 100 young men with Norwegian citizenship have travelled to Syria to participate in the civil war, NRK reports, quoting Muslim sources.
This is a much higher number than so far estimated by the Norwegian intelligence service.
They have estimated that more than 20 radical Norwegian Islamists are in Syria at this time, and that at least seven of them are fighting on the side of Al Qaida.
In Syria, the Norwegians are receiving training in the use of arms and explosives, and the intelligence service fears that this experience may later be used in Norway.
