ZOETERMEER, Netherlands (AP) — The Dutch national intelligence agency said Tuesday that threats targeting the Netherlands are increasingly connected to worldwide turmoil, including the wars in Gaza and Ukraine.

Although the number of terror attacks across Europe has been down in recent years, the General Intelligence and Security Service in its annual report said the Israel-Hamas war in Gaza and the destruction of a Quran outside parliament last year are “trigger events” for extremists.

“The terrorist threat is serious at this moment,” the agency’s director-general, Erik Akerboom, told The Associated Press.

Akerboom said he is particularly concerned about big events, noting that the agency is working closely with French authorities to prevent incidents during the Paris Olympics this summer.

In December, the Dutch counterterrorism agency increased the country’s threat alert to its second-highest level because of concerns about the Islamic State group’s Khorasan affiliates, Akerboom said. IS-K, a Central Asian affiliate, was responsible for the attack at a suburban Moscow concert hall that killed at least 133 people in March.
