The Terrorists Migrating into Europe
"Based on French intelligence material, a clandestine 'external operations' division of ISIS in January 2014 sent its first of 'at least' 21 well-trained operatives to Europe camouflaged among refugee and migrant flows...more fighters trained by ISIS in Syria traveled the migrant routes alone or in pairs at the rate of every two to three months through the balance of 2014 and early 2015" according to the Times."
In Germany, the Federal Intelligence Service (BND) warned in 2016 that Islamic State fighters had come into
Europe disguised as refugees and that Islamic State leaders were training the
fighters on how to apply for asylum.
