However despite the current threat level of a possible terrorist attack in Netherlands remaining at 4 on a scale from 1 to 5, there are no specific indicators that an attack is being prepared, the report said.
"If the ISIS [Daesh] ‘caliphate’ is defeated militarily or collapses, the number of returnees is expected to rise. An increasing number of returnees will probably strengthen the domestic jihadist movement in the Netherlands and thus magnify the threat it poses," the report said.
According to the report, the Dutch jihadist movement, which consist of several hundred actual members and a few thousand sympathizers, have adherents in the Netherlands, Syria and Iraq, as well as in other countries. Dutch jihadists may act as attackers, facilitators or accomplices within the ranks of international terrorist networks, such as the Daesh, al-Qaeda and others, the report said.
"Jihadists living in the Netherlands could respond to the repeated calls by ISIS and al-Qaeda to commit terrorist violence in one’s own country," the report added.
Severe political polarization may pose another threat to the Dutch security as political division between far right and far left parties on controversial issues such as Islam, immigrants, integration and EU-Turkey relations could also create the basis for possible acts of violence by a lone individual, according to the report
The report represents the 43rd terrorist threat assessment for the Netherlands, and it analyzes the level of foreign and national threat to the country based on information collected by intelligence and security services as well as police and other sources.
