When responding to a Sky News question whether there is a guarantee that attacks similar to those that happened in Paris last week would not happen again, Wainwright said "No, there can't be, otherwise what happened in Paris wouldn't have happened. I think there is a realization across the police and security community in Europe.”
However, Wainwright added that the authorities are doing everything possible to ensure security in the region, highlighting that police response has become more advanced.
Earlier in the day, Belgium has deployed troops alongside police to protect the country amid increased terrorist threat, while security has also been tightened in several other European countries. The measures came in response to last week’s terrorist attacks in France, when Islamist extremists killed a total of 17 people in three different attacks in the Paris area.
Europe now faces threat from those militants, who travelled to Syria and Iraq, and other war-torn regions to join the Islamic State (IS) militant group and other extremists. Those young fighters often return back to home countries aiming to conduct terrorist attacks on behalf of the radical organizations they are involved with.
According to Wainwright, up to 5,000 people from Europe might have been radicalized as they travelled to Syria and Iraq.
