Terror Threats: Arrests for jihadist terrorism treble in EU

The European Union is facing an “elevated threat” from Islamic extremists with a trebling in jihadist arrests in the last two years, according to the EU police agency.

Europol warned that lone actor attacks remain a “favourite tactic” of Islamic State and al-Qaeda.

It pointed out that both terror groups have repeatedly called on Muslims, “often radicalised within a short space of time”, to perpetrate attacks in the countries they live in.
