About 65 African migrants have broken through a border fence between Morocco and the Spanish enclave of Melilla, two days after another mass border charge.
Spanish authorities have been trying to reinforce the border fence
They got through when 500 people rushed the fence as authorities worked to strengthen it, Spanish police said.
Many who succeeded in crossing into Melilla were injured by razor wire.
In the past two weeks 2,000 people have stormed the borders between Morocco and Spain's enclaves of Ceuta and Melilla.
Last week, Spain and Morocco deployed hundreds of police and soldiers to try to keep immigrants out.
On Thursday five people were crushed to death while trying to break into the other Spanish enclave of Ceuta.
Melilla and nearby Ceuta are seen as stepping stones to Europe by African migrants.
