The Netherlands’ anti-terrorism ‘tsar’ Tjibbe Joustra says he is extremely worried about films on the internet showing potential terrorists how to make explosives and suicide-bomb belts. The videos are currently in Arabic but Joustra is concerned they may soon crop up in Dutch.

The internet is fast becoming an online training camp, Joustra said on current affairs TV show Nova on Monday night.
A report released today by the anti-terrorism centre NCTb, warns that terrorists and radical Muslims were increasingly turning to the internet to spread propaganda. But launching an attack on the internet itself – or using the internet to hack into vital control systems in, say, a chemical company – was extremely unlikely, the report concludes.
‘Internet is crucial for… forming virtual networks, training purposes and propaganda,’ it says. ‘Spreading propaganda via internet is approached professionally, has a wide reach and relatively little counter-argument.’
Joustra said there were between 100 and 200 radical Islamic Dutch websites in operation but action had only been taken against a handful. After the murder of Theo van Gogh by an Islamic extremist, the government had pledged to shut down radical sites.
Sociologist Albert Benschop told BNR Nieuwsradio it was extremely difficult to take action against websites which were hosted by a foreign providers.
