The war between Israel and Hamas and irregular border crossing attempts have led several EU countries, including Germany, Slovenia, Croatia, and Italy, to reintroduce border controls.
The Schengen Code allows member states to reinstate internal control in specific emergency situations – such as where national security is threatened, but this does not mean a return to the types of border controls that existed before the Schengen Agreement.
Slovenia announced stricter controls at borders with Hungary and Croatia, lasting at least ten days. Croatian Prime Minister Andrej Plenkovic also introduced similar measures with Slovenia, stating that these are not hard border checks but that a change in the security context following wars and instability in the southern and eastern part of Europe made it necessary. Italy also suspended an open-border agreement with Slovenia for ten days and the German Interior Ministry announced temporary frontier checks at the borders of Czechia, Poland, and Switzerland on October 16.
Austria, Poland, and Czechia also extended controls on their common borders with Slovakia until November 2.
