In 2024, one third of those arrested for terrorism-related crimes in the European Union were between 12 and 20 years old.

• The Europol TE-SAT 2025 report states 'almost one third' — not exactly 'one third' — of terrorist suspects were under 20. The claim rounds this to a precise one third.
• The age range in Europol's data is 'under 20' (typically meaning ages 0–19), whereas the claim specifies 'between 12 and 20 years old', which extends the upper bound to include 20-year-olds and adds a lower bound of 12 not present in the source.
• The TE-SAT 2025 report indicates the 'more than one third' figure applies specifically to suspects arrested on jihadist terrorism charges, not necessarily uniformly across all terrorism categories. The claim does not distinguish between terrorism typologies.
• The Europol TE-SAT 2025 was published on 24 June 2025, covering data from 2024, so the MEP could have known this data at the time of the session (20 May 2026), though the claim attributes the finding broadly to 'Europol' without specifying the TE-SAT report.
