While some of the immigrants climbed the wall, others threw objects at border guards that were trying to stop them. Six guards were treated for minor injuries and an immigrant suffered a broken leg after falling from the fence and was transferred to the Hospital of Melilla.While some of the immigrants climbed the wall, others threw objects at border guards that were trying to stop them, the government said.Spain has two enclaves in Morocco, Ceuta and Melilla.The migrants were taken to an internment center where Spain attempts to establish their identity and nationality.
