Why are these Republicans so afraid of widows and orphans?
Police sources said one of the suspects had a hand-drawn picture of a planned route from Turkey to Germany, via Greece, Serbia and Hungary.
It is believed the group are Islamic State militants planning to make their way to Germany posing as refugees.
The Anadolu Agency said the group arrived in Istanbul from Casablanca, Morocco, and were interviewed by criminal profiling teams at Ataturk Airport.
Anadolu said the eight claimed to be tourists visiting Istanbul but a hotel refuted claims they had reservations there.
The arrests come as Europe is on high alert following the terror attacks in Paris which have left 129 dead and hundreds injured.
The arrests come after an ISIS terrorist bragged about how easy it was to smuggle thousands of covert jihadists into Europe under the guise of being a desperate refugee.
The Syrian operative claimed more than 4,000 covert ISIS gunmen had made it into western nations, hidden among innocent refugees.
He said members of the blood-thirsty group were following the well-trodden route taken by refugees and migrants fleeing Syria, travelling across the border of Turkey then on to boats across to Greece and through Europe.
The man claimed there are now more than 4,000 covert ISIS gunmen “ready” to strike across the European Union.
Yet with knowing all this our president had an ugly temper tantrum Tuesday night with his nonsense about Republicans fearing widows and orphans. He looks more ridiculous by the minute.
