French President Emmanuel Macron called for a “deep overhaul” of the Schengen zone, Europe’s open-border area, urging the EU to set up a “real police force” and deploy it at its external borders. “We see very clearly that terrorist actions can actually be led by some people who use migratory flows to threaten our territory,” Deutsche Welle quotes Macron as saying while visiting the town of Le Perthus near the Spanish border on Thursday. Flanked by Interior Minister Gerald Darmanin and European Affairs Minister Clement Beaune, Macron also announced France would be doubling the number of guards at its national borders from 2,400 to 4,800 due to the escalating terror threat.
