ISIS has flooded Europe with 1,500 highly-trained terrorists ‘ready to launch attacks’, chilling EU report claims

Around 30 to 35 per cent have returned with “specific missions”, while the other half  remained in the battle theatre – which amounted to between 2,000 and 2,500 Europeans.

This means as many as 1,750 may have returned, based on the percentages listed in the report which EU counter-terrorism coordinator Gilles de Kerchove will present to EU interior ministers on Friday.
