Large numbers of sub-Saharan migrants have stormed the border crossing between Morocco and the Spanish enclave of Ceuta, running past guards.
It’s not clear how many people managed to cross, although some estimates put it as high as 300.
The Red Cross says it has attended to more than 180 people who have been taken to a reception centre.
It follows a similar event on Tuesday when 200 migrants crossed a high fence from Morocco into the Spanish territory of Ceuta.
Migrants regularly try to climb the high fences that surround the territory, but the authorities say mass attempts to pass the border crossing are rare.
Ceuta and another Spanish enclave, Melilla, are the only parts of the European Union in Africa.
