More than 200 police commandos took part in the pre-dawn raids in northern Germany to detain the men, who were suspected of either plotting an attack or awaiting orders to commit one.
The men were identified only as Mahir al-H., 17, Ibrahim M., 18, and Mohamed A., 26, in a statement issued by federal prosecutors.
They left Syria last October and travelled via Turkey and Greece – a route used by tens of thousands of refugees and migrants – and arrived in Germany in mid-November.
Interior Minister Thomas de Maiziere said the three apparently used the same migrant trafficking network as several of the Isis gunmen who killed 130 people in Paris in November last year.
Prosecutors said in their statement that Mahir al-H. had joined Isis in its de facto capital of Raqqa, Syria by September 2015 and received some weapons and explosives training.
The following month, all three men had pledged to travel to Europe in talks with an Isis fighter who was “in charge of missions and attacks” outside of the Syria-Iraq region where the group has its self-proclaimed caliphate.
They were detained at three refugee shelters in the northern state of Schleswig-Holstein by more than 200 commandos of the federal police, BKA and police forces of several states.
Police also raided several other asylum seeker shelters, Die Welt daily said.
German authorities have urged the public not to confuse migrants and “terrorists,” but have acknowledged that more jihadists may have entered the country among the around one million asylum seekers who arrived last year.
I wonder why anyone would confuse the two?
Now remember Obama’s assurances about how thoroughly screened his 10,000 Syrian Muslim migrants are? Just wait.
