Spanish authorities are trying to identify criminals and radical Islamists in the Spanish enclave and exclave of Ceuta on the northern coast of Africa after a mass influx of illegal immigrants from Morocco, the Confidencial newspaper reported on Monday.

The special services are considering the theory that radical Islamists or jihadists from the towns surrounding Ceuta could have mixed with the crowd to enter Spanish territory, Spanish law enforcement sources said.

Currently, the Spanish Guardia Civil and police are analyzing video footage of the mass invasion of Ceuta and combing the streets of the city in order to quickly identify the perpetrators of the violent acts, as well as possible jihadists who took advantage of the border chaos to enter Spain.

 The special services have deployed all available resources to plug the security breach, a source at the Spanish interior ministry said.

It is not yet clear how many people have entered and left Ceuta in the past week, although Spanish Prime Minister Pedro Sanchez’s government is trying to show that the situation is under control and reassure its European Union (EU) partners.

An urgent meeting of EU interior ministers is scheduled for Tuesday on the matter. In particular, the leaders of the 22 countries said that ministers should consider strengthening support for the EU border agency Frontex and improving EU cooperation with Morocco.

Tens of thousands of migrants have illegally crossed from Morocco into the Spanish enclave and exclave of Ceuta in northern Africa in recent days. On Saturday, however, Spain said the situation had practically settled.
