Morocco stepped up security measures Friday in the northern city of Fnideq and other areas ahead of social media calls for a mass attempt to cross into the Spanish-administered enclave of Ceuta, Anadolu reports.

An Anadolu correspondent said authorities reinforced checkpoints leading to Fnideq, as well as the northern cities of Tetouan, Tangier, and Nador.

Authorities also installed barbed wire along the border crossing between Fnideq and Ceuta while deploying large numbers of security personnel and auxiliary forces across the city.

The measures came ahead of Aug. 15 after Morocco’s Interior Ministry said it had detected anonymous social media calls urging a mass illegal crossing into the Spanish enclaves of Ceuta and Melilla.

On Wednesday, Interior Ministry spokesperson Rachid El Khalfi said authorities had monitored anonymous posts and messages circulating on social media in recent days encouraging attempts to organize an illegal mass crossing into the two enclaves.
