In the past year, several EU Member States have successfully prevented attacks by Islamist terrorist groups, which aimed to cause mass casualties. During 2010, 179 individuals were arrested for offences linked to Islamist terrorism, representing a 50% increase compared with 2009. Furthermore a higher proportion of those arrests related to the preparation of attacks in the EU (47% compared with 10% in 2009).
Mens statistikkerne over vellykket gennemførte terrorangreb stadig domineres af socialistiske separatister og anarkister, så er muslimske terrorister stadig de eneste der forsøger sig med angreb der skal begå massemord på civile. To blev forhindret sidste år.
