With the number od wannabe independance movements in the United States of Europe it is hardly surprising other terrorist movements exist and the rampage of a lone wolk can never be eradicated.

HOWEVER:
In 2016, a total of 142 failed, foiled and completed attacks were reported by eight EU Member States. More than half (76) of them were reported by the United Kingdom. France reported 23 attacks, Italy 17, Spain 10, Greece 6, Germany 5, Belgium 4 and the Netherlands 1 attack. 142 victims died in terrorist attacks, and 379 were injured in the EU. Although there was a large number of terrorist attacks not connected with jihadism, the latter accounts for the most serious forms of terrorist activity as nearly all reported fatalities and most of the casualties were the result of jihadist terrorist attacks. Explosives were used in 40% of the attacks and women and young adults, and even children, are playing increasingly operational roles in committing terrorist activities independently in the EU. Most arrests were related to jihadist terrorism, for which the number rose for the third consecutive year. Also, the European Counter Terrorism Centre at Europol supported 127 counter terrorism investigations in 2016, which shows a clear indication of the growing range of jihadist activity.
