On 23 June 2020, Europol published its new Terrorism Situation and Trend Report (TE-SAT) 2020. It outlines the latest developments with regard to jihadist, ethno-nationalist and separatist, left-wing and anarchist, right-wing, and single-issue terrorism.

Unfortunately, the year 2019 has seen a fairly new security threat caused by individuals imprisoned for terrorist offences and inmates who radicalised in prison, both during their imprisonment and after release. Several attacks within prisons that occurred in 2019 seem to demonstrate this threat.

Looking at jihadist terrorism, the number of incidents dropped from 24 in 2018 to 21 in 2019, out of which the majority (14) were foiled incidents.

In the area of ethno-nationalist and separatist terrorism, the report reveals that the attacks specified as ethno-nationalist and separatist terrorism represented the largest proportion (57 of 119) of all terrorist attacks in 2019, with all but one incident related to Dissident Republican (DR) groups in Northern Ireland. The separatist terrorist group Euskadi ta Askatasuna (ETA) in Spain continued to be inactive in 2019.

111 arrests on suspicion of left-wing and anarchist terrorism as well as 21 arrests on suspicion of right-wing terrorism were conducted, with Italy being most affected.

In total, 119 foiled, failed and completed attacks were reported by 13 EU Member States in 2019, compared to 129 in 2018. 1,004 individuals were arrested in 19 EU Member States on suspicion of terrorism-related offences, with Belgium, France, Italy, Spain and the UK reporting the highest numbers.

Ten people died as a result of terrorist attacks in the EU and 27 people were injured.
