Europol has coordinated the largest Referral Action Day (RAD) to date targeting terrorist propaganda shared through audio content, resulting in the referral of 17 298 URLs across 40 online platforms. Combined, the audio content in these links represents more than 1 100 hours – the equivalent of 47 days of continuous listening. The operation focused on terrorist audio propaganda used by groups across the ideological spectrum, including jihadist and violent right-wing extremist networks.
