European nations are rapidly reinstating border controls in response to rising concerns over mass migration and security threats. France, Germany, and several other countries have introduced emergency checks at internal borders, citing fears of terrorist infiltration and public order risks. The French government has specifically pointed to Britain as a destination for radicalised individuals crossing through France, prompting stricter measures at key border points.
The situation has drawn international attention, with leaders from the United States and prominent figures in Britain warning of the dangers posed by uncontrolled migration. Recent reports from the European police agency highlight a surge in terrorist attacks and arrests, with a notable increase in jihadist activity and involvement of young people. As a result, the foundational principle of free movement across much of Europe is now under unprecedented strain.
