Elsewhere in the annual report, the Czech Republic’s counter-intelligence service BIS says seven people left the Czech Republic last year to join some terrorist organisations, such as Islamic State. According to the report, these people were originally from Islamic countries and stayed in the Czech Republic for a short space of time. The report says their return to the country would present serious security threat due to their possible participation in a terrorist attack. BIS recorded only several Czechs sympathizing with radical Islam; most of them were mentally unstable.
