Spain and Morocco have tightened security along the border with the Spanish exclave of Ceuta after calls circulated on social media urging another mass influx of migrants into the North African territory on Saturday.

Despite the heightened security presence, a dpa reporter observed calm at the main border crossing in Ceuta during the morning. Spain’s state broadcaster RTVE and other media outlets in the exclave reported similar conditions.

Authorities in both countries are seeking to prevent a repeat of the events at the end of July, when, according to various estimates, as many as 80,000 migrants attempted to enter Ceuta in a mass surge.

Spanish Interior Minister Fernando Grande-Marlaska recently said the incident was a one-off event and insisted it would not happen again.

A few days ago, Morocco’s Interior Ministry announced the arrest of a group of people suspected of inciting further attempts to illegally enter the Spanish exclaves of Ceuta and Melilla.
