Dozens of sub-Saharan migrants crossed into Spain from Morocco after running through a border gate into the enclave of Ceuta, emergency services said.
Migrants frequently attempt to storm the borders of Spain’s two enclaves in northern Africa, Ceuta and Melilla, clambering up 6m fences topped by razor wire.
On Monday a group of more than 100 migrants ran through a gate in the fence used for border control, surprising Moroccan and Spanish security forces, a Reuters witness said.
The Red Cross said it assisted 186 people following the morning rush across the border, adding four migrants were hospitalised.
Once inside Spain’s enclaves, migrants are usually taken to temporary shelters and later moved to the Spanish mainland or returned to their country of origin.
Many migrants try to enter Spain as a way to other parts of Europe. Arrivals through Ceuta and Melilla, as well as the number of migrants attempting to cross into Spain by sea from North Africa has risen this year, although the route between Libya and Italy remains the most popular.
The Red Cross said last week it assisted 7,400 migrants crossing into mainland Spain and Ceuta and Melilla so far this year, up from 3,600 in the same period a year ago.
