More than 50 Moroccan and Spanish border guards have been injured repelling about 1,100 African migrants who attempted to storm a border fence and enter Spain's North African enclave of Ceuta, according to Spanish authorities.
A regional government spokesman said 50 Moroccan and five Spanish officers were injured when hundreds of migrants tried to enter Spanish territory.
The spokesman said two migrants managed to reach Spanish soil. Both were injured scaling the 20ft border fence and were taken to hospital by Spanish police.
Another 100 migrants climbed the fence, but Spanish agents sent them straight back to Morocco.
Last month, more than 400 migrants breached the fence at Ceuta.
Hundreds of sub-Saharan African migrants living illegally in Morocco try to enter Ceuta and Melilla, Spain's other North African enclave, each year in hope of getting to Europe.
Most migrants who try to cross are intercepted on the spot and returned to Morocco. Those that make it over the fences are eventually repatriated or let go.
Thousands more try to reach Europe by crossing the Mediterranean Sea, often in small craft unfit for the open sea.
Also on Sunday, a ship of Spain's maritime rescue service rescued 52 migrants trying to reach Spain's southern coast in a small boat.
