ISIS supporters have gloated about sleeper cells nestled in Europe which are poised to carry out horror attacks on innocent civilians.
And most frighteningly of all – terror experts have backed up the chilling claims.
During the migrant crisis it was feared jihadists could sneak through the European Union’s porous borders as thousands arrived into the continent daily from war-torn nations.
Now its reported that online material has been seen from ISIS supporters, claiming sleeper cells are waiting to attack. One ISIS supporter boasted about upcoming attacks which he claimed would be as deadly as those in Nice and Paris.
Political scientist Colin Clarke from the American think-tank RAND has warned Europe not to take the claims lightly.
