Two Dutch suicide bombers have died in attacks in Iraq and Syria, home affairs minister Ronald Plasterk said on Wednesday at the publication of the secret service’s annual report.

One man was involved in an attack on citizens in Iraq using a wired-up rucksack. The other set off a car bomb in Syria, the minister is quoted as saying. He declined to give any further details.

The security service estimates around 100 Dutch nationals have gone to fight with rebels in Syria and at least 20 have since returned to the Netherlands. This, the AIVD says, brings potential threats with it.

The AIVD report also shows the impact of digital spying on the Netherlands, saying the country is particularly vulnerable because of its high value IT structure.
