Millions of civilians have been displaced both internally and externally. For various reasons, refugees find Europe as their best destination to seek refuge and start a new life away from the war-ridden Middle East.
The terrorist attacks in Paris in November 2015, however, prompted fears across Europe that a small number of the Islamic State (ISIS) terrorists might have slipped into the EU disguised as refugees. The first evidence came from Hungary. A suspected ringleader Salah Abdeslam visited Keleti station in Budapest and ‘recruited’ a team from unregistered refugees.
This gave rise to a common concern all over Europe and gave an incentive to control the external borders with special focus on identifying Sunni radicals who might pose a security threat. EU Member States are also working on improving proactive intelligence sharing on terror suspects within the EU and with other international allies.
