Few of those Danes who have travelled to Syria to fight in that country’s civil war face legal action when they return home, according to sources within the Muslim community.

One of the reasons, said Jørn Vestergaard, a professor of law at the University of Copenhagen, may be a lack of evidence that they have committed any crime.

It is estimated that between one and ten percent of all foreign fighters later take part in terrorist attacks in their home countries, and that the terrorist acts they commit tend to be more effective than those committed by individuals who do not have combat experience.

Domestic intelligence agency PET has described returned foreign fighters as one of country’s biggest security concerns but had no comment to the claim.
