Moroccan police have arrested more than 100 people attempting to reach the Spanish enclave of Ceuta, following a reported disinformation campaign on social media encouraging migrants to travel to the territory.

Footage posted online on Saturday showed large crowds of people, most reportedly from sub-Saharan Africa, heading towards Ceuta. The attempted crossing comes just weeks after approximately 72,000 people entered the enclave in late July, with at least 96 dying in the process.

Hundreds of police officers were reportedly deployed to confront the crowds. Officers used tear gas to disperse the groups, leading to at least 111 arrests, according to sources citing Morocco's Ministry of Interior.

Local news outlet Le360 reported on Saturday afternoon that as many as 294 people had been arrested, including 46 Moroccans. The remainder were reportedly from sub-Saharan Africa.

The crowds advanced through mountainous terrain on their way to Ceuta, passing through Fnideq, a coastal town in northern Morocco. They are believed to have chosen the mountain route to avoid security checkpoints.

A Spanish newspaper reported that hundreds of people were travelling towards the enclave, which Morocco does not recognise as Spanish territory. Moroccan authorities had said earlier in the week that they were working to foil any such attempts.

The latest crossing attempt also follows what has been described as a new disinformation campaign on social media encouraging people to travel to Ceuta.

Spanish lawmaker Jaime de los Santos, deputy secretary of education for the conservative People's Party, accused Prime Minister Pedro Sanchez of failing to address the crisis, which he said began on July 30.

Sanchez is currently on holiday at the Royal Residence of La Mareta in Lanzarote, a common destination for Spanish prime ministers.

"It's Saturday, August 15th, and the week of the eclipse has already passed. Sixteen days have gone by since Spain was invaded by more than 80,000 Moroccan citizens, and Pedro Sanchez is still hiding in La Mareta without giving any explanation, without putting a stop to this crisis, and using his ministers to cover up his shameful actions," De los Santos said in a statement.

Interior Minister Fernando Grande-Marlaska said on Thursday that approximately 5,000 migrants remained in Ceuta.
