There is a sharp increase in both the number of incidents and the deaths caused by different types of attacks in Europe recently. The assailants claimed these attacks either on behalf of Islamic State in Iraq and Levant (ISIL) or as "lone wolves" with no direct affiliation to the ISIL. However, there has been some change in the way some of the attacks were carried out. Also, there was a shift in their target selection. Security experts and authorities have indicated significant factors contributing to this development. This paper examines the apparent alarming trend in the change of terrorist modus operandi in Europe. The authors gathered a dataset from various open sources, primarily from Global Terrorism Database (GTD). The findings reveal that terrorists’ modus operandi -- techniques, tactics, and procedures (TTP) -- has been influenced by international events and conflicts.
