The Dutch General Intelligence and Security Service (AIVD) has said the Islamic State in Iraq and the Levant (ISIL, or ISIS) is using Turkey as a strategic base to reorganize, posing a threat to the security of Europe, the Kurdistan24 news website reported.  In a report published on Monday, AIVD said that after the start of the Syrian conflict, Turkey “was for a long time a springboard for an unprecedented number of foreign fighters who traveled to Syria from all over the world.”  “ISIS (and also Al Qaida) use Turkey as a strategic base,” the report said. “From here, ISIS can recover, reorganize and further shape the underground struggle in the region.” AIVD also said the extremist group was able to exploit “the relative peace in Turkey to forge plans to (re)shape its still present international ambitions.”
