Gilles de Kerchove also warned that Western air strikes would increase the risk of retaliatory attacks in Europe.
The number of Europeans joining ISIL terrorists has surged to about 3-thousand over the past few months.
That’s according to E-U Counter-terrorism Chief Giles de Kerchove. He said the figure was just 2-thousand several months ago, but it has now increased by one thousand. The EU counter-terrorism chief said the rise might be due to the ISIL terrorists’ declaration of a caliphate in Syria and Iraq.
