Reports have raised concerns that Islamist extremists may have entered Europe undetected during a mass crossing at Ceuta, the Spanish enclave in North Africa, with some individuals reportedly boasting online or to reporters that they crossed the border successfully. The claims add to long-running anxieties in Spain and the wider EU about border security at Ceuta and Melilla, which have repeatedly seen large groups attempt to cross from Morocco, and about the vetting of arrivals once they reach European soil.

The article, as provided, does not include further verified detail on numbers, dates or official statements from Spanish or EU authorities confirming the extremism fears or the criminal boasts referenced in the headline. It appears alongside unrelated Daily Mail content covering UK politics, royal news and celebrity stories, meaning the specific facts, sources and timeline of the Ceuta claims are not available in this excerpt.
