Dozens of Dutch citizens are fighting with rebels in Syria and could return home battle-hardened, traumatised and even further radicalized, the chief of the Netherlands' top intelligence agency has warned.
In a rare interview with Dutch television aired yesterday, Rob Bertholee, head of the General Intelligence and Security Service, said the number of Dutch nationals heading to Syria was growing fast.
In my view, that is very worrying because of the combat experience they acquire, the ideological convictions and the fact that they could become traumatised there," Bertholee told Dutch current affairs show Nieuwsuur.
There have been no terror attacks in the Netherlands for years, but authorities have warned of the growing risk of
Muslims going overseas to fight for their faith and then returning home.
A terrorism expert said today that images of Syrian President Bashar Assad's brutal crackdown on rebels is drawing
fighters, not only in the Netherlands but from across Europe.
Peter Knoope, director of the International Centre for Counter-Terrorism in The Hague, said the real problems could
emerge when the Syrian civil war finally ends.
He said that after conflicts like the one in Syria, "You always have some sort of proliferation of fighters who go
somewhere else... They have been taught to fight, and some of them do not know how to stop."
In the only reported Dutch case of would-be jihadists, police in the port city of Rotterdam arrested three men in
November on suspicion of preparing to travel to Syria to fight alongside rebels. The men, whose identities have not been released, are due in court next month.
The Dutch assessments came as France also expressed concerns about its citizens heading to Mali to join radical
Islamic fighters there, even as the French army is fighting the Muslim rebels in its former colony.
French police arrested four youths this week suspected of trying to join radical Islamic fighters in West Africa, and expelled radical imams and others considered risks to public order.
