European security officials report a growing risk of attacks by Islamists radicalized by the war, with the biggest threat likely to come from "lone wolves" who are difficult to track, the Guardian reported.
More than 10 intelligence and police officials in 5 European countries, including Britain, Germany and France, said they were increasing surveillance of Islamist militants.
It will further strain resources already under pressure from dealing with the perceived threats from Russia, China and Iran, which London's chief constable Mark Rowley called "one of the biggest confluences of threats I have ever seen".
A British security official said the war in Gaza was likely to become the biggest catalyst for the formation of Islamist militants since the 2003 Iraq war and that calls for attacks on Jewish and Western targets had increased in Europe.
A German intelligence source said the threat to civilians was the highest in Germany's recent history, with threats coming from Islamist militants, far-right groups and Russia.
Twin attacks by Islamist militants in France and Belgium last month killed three people and those two countries, as well as Austria, Slovenia and Bosnia and Herzegovina, raised their terror alert levels. Italy has restored border controls with Slovenia, citing the risk of militants entering the country. /BGNES
