Moroccan police arrested at least 111 people on Saturday as they tried to enter Spain's North African enclave of Ceuta, amid tightened security on both sides of the border after social media posts called for another mass migrant crossing.

The annoucement comes as calls resurfaced on social media for mass crossings into the Spanish enclave in North Africa.

Moroccan authorities on Wednesday announced measures to counter a new influx of migrants to the Spanish territory of Ceuta, after monitoring a new wave of online disinformation.

Morocco has mobilised hundreds of riot police and eight naval vessels near Ceuta amid online calls for another mass crossing on August 15
