In June 2018, Europol published its Terrorism Situation and Trend Report (TE-SAT) for 2018, outlining current trends.

According to the figures for 2017, the report counts 205 foiled, failed, and completed terrorist attacks, which nine EU Member States reported, with the UK experiencing the highest number of attacks (107). Unfortunately, 2017 saw a reversal in the downward trend observed since 2014, with a 45% increase in 2017 compared to 2016 when 142 attacks had been reported. Attacks specifically classified as ethno-nationalist and separatist accounted for the largest proportion at 67%, Jihadist attacks account for 16%, left-wing attacks for 12%, and right-wing attacks for 3%. Despite the higher number of attacks reported in 2017, the number of arrests in the EU for terrorism-related offences amounted to 975 compared to 1002 in 2016. The average age of those arrested was 30, with 45% of the suspects falling in the range of 20-30 years of age; 25% in the range of 30-40 years of age. More than 80% of the arrestees were male. The relative amount of EU citizens among the arrestees comprised 50% and lies between the percentages of previous years (58% in 2015; 43% in 2016).
