Europol, the central police office of the European Union, is warning that ISIS has set up secret training camps across Europe to prepare fighters to carry out “special forces style” attacks in the UK or other EU countries. The police office said the camps provide survival training and sports activities to help jihadists prepare for “combat and interrogation resistance”. And ISIS could look to recruit refugees who have fled to Europe to launch terror attacks in the countries that have given them shelter, the agency said. Europol refused to say in which countries the camps were suspected to have been set up but security and police sources last night said they were not aware of any in the UK.
