At least 800 Islamist extremists have returned from Syria or Iraq to Europe and are ready to carry out terrorist attacks, according to Spanish counter-terrorism sources.
This list includes those believed to have been recruited by the Islamic State, Al-Qaeda and affiliated groups.
“These people are not well trained, but they are poised and prepared to do anything” the source told Spanish radio station Cadena Ser. “Once they have been indoctrinated, they receive the minimum training.”
The revelations come with news that Spain and Morocco have detained 14 people in a joint counter-terrorism operation on suspicion of recruiting for the Islamic State.
Spanish intelligence agencies have said approximately 150 Spanish terrorists have joined ISIS in Syria and Iraq.
They also mentioned that there are increasing numbers of women and children among those who have been recruited in Spain. Security sources said that the people recruited by ISIS are becoming suicide bombers and also slaves.
The sources also said there are no Spanish terrorists in terror in Mali and Libya, even though ISIS operates in those places.
An additional 350 Islamic State terrorists are believed to have returned to the UK and may be preparing to carry out attacks there.
Over the weekend an attack on train in France was narrowly thwarted by the swift actions of five passengers.
The Islamic State has threatened to carry out terrorist attacks on several European countries. Last week notorious executioner Jihadi John resurfaced in a new video threatning to return to the UK and carry out terrorist attacks.
Law enforcement agencies across Europe are tracking returned jihadists and other Islamists. They have also thwarted several plots. In early August, UK security sources revealed they had foiled an Islamic State plot to kill the Queen at the VJ Day celebrations.
American law enforcement has also stopped many potential terrorist attacks. In July the Chair of the House Homeland Security Committee Michael McCaul revealed that U.S. security services have stopped “over 60” Islamic State plots so far this year.
