Following calls on social networks to cross the barrier at Ceuta, a Spanish exclave in northern Morocco, the Moroccan authorities this weekend stepped up security at the border to prevent any attempts at illegal entry and to maintain public order. In mid-September, hundreds of people, including Moroccans and migrants from other parts of Africa, as well as minors, headed for the village of Fnideq in a bid to force their way in. Ceuta and its sister territory of Melilla, wedged on the North African kingdom's Mediterranean coast, have long been a magnet for irregular migrants, being the only European Union territories that share a land border with the African continent.
