On Tuesday, German police special forces arrested three Daesh suspects in northern Schleswig-Holstein federal state.

"The glaring gaps in controlling the immense flood of refugees, especially in the autumn of last year, is exacting revenge. We know in the meantime that IS has also purposefully used these vulnerabilities so that attackers can be smuggled into Europe disguised as refugees," Herrmann told journalists of the Funke Mediengruppe, as quoted by DPA news agency.
The European Union is currently struggling to manage a massive refugee crisis, with hundreds of thousands of people leaving conflict-torn countries in the Middle East and North Africa to escape violence and poverty and seeking asylum in Europe. In 2015, more than 1 million migrants and asylum seekers arrived to Germany.
