Juan Jesus Vivas, the regional president of Ceuta, said nearly 60,000 migrants had entered the Spanish enclave from Morocco within the past 24 hours, overwhelming local authorities and triggering violent clashes at the border.

Dozens killed during crossing attempt

According to Rachid Sbihi, head of a local workers' association representing Civil Guard officers, several migrants drowned while trying to swim across, while others died in a stampede near the breakwater fence at Tarajal beach, close to the Moroccan border checkpoint.

The fatalities came as thousands of migrants attempted to enter the Spanish territory, marking one of the largest border breaches in recent years.

Sanchez condemns border breach

Spanish Prime Minister Pedro Sanchez travelled to Ceuta on Friday to assess the situation and condemned the mass crossing, describing it as "a violation of Spain's territorial integrity."

Blaming organised human trafficking networks for the tragedy, Sanchez said smugglers exploit vulnerable people with false promises.

"They deceive so many young people and ultimately lead many of them to their deaths—whether in the ocean or, as in this case, at Spain's border in the autonomous city of Ceuta," he said.

Spain steps up security

Spain's Interior Ministry said nearly half of those who crossed into Ceuta had already returned to Morocco.

The ministry also released footage showing migrants walking back through a border gate.

To contain the crisis, Madrid has deployed additional troops, police personnel, divers, drones and patrol boats to reinforce security around the enclave.

Videos circulating on Thursday showed thousands of migrants entering Ceuta in a dramatic surge that caught authorities off guard.

Crisis sparks diplomatic tensions across europe

The unprecedented influx has triggered diplomatic concern across Europe, with several countries backing Spain while calling for stronger border controls.

European Commission President Ursula von der Leyen described the scenes in Ceuta as "unacceptable" and stressed that entry into the European Union must comply with established rules.

"We cannot allow anyone to come to our European Union without abiding by our rules," she said.

An EU official later said there was no indication that migrants had moved onward from Ceuta into mainland Europe.

Meanwhile, France tightened checks along its border with Spain, while Germany, Italy and Finland condemned the developments.

Italy also called for Spain's suspension from the Schengen free-travel area, a move supported by Finland and Denmark. France and the United Kingdom said they were prepared to assist Spain in managing the crisis.

Trump weighs in

The migrant surge also drew political reactions from the United States.

US President Donald Trump used the developments in Ceuta to criticise Democrats, warning that the United States could face a similar situation under a Democratic administration.

"It's terrible. Remember that picture. That's going to be us in three years if the wrong side gets in," Trump was quoted as saying. "If the Democrats get in, you will not live a very good life."

The crisis continues to test Spain's border management capabilities while raising fresh concerns over migration, security and cooperation between the European Union and Morocco.
