More than 200 African migrants have scaled the border fence into the Spanish enclave of Melilla.
It was the biggest assault on the border in more than eight years.
The migrants, many from Cameroon and Guinea, ran through the Melilla streets after making it onto European soil in the early hours of February 28.
They headed for the overcrowded migrant reception centre in celebratory mood.
The latest incursion at Melilla brings the number of migrants who have successfully scaled the fence to almost 600 so far this year.
The Spanish territories of Melilla and Ceuta in Northern Morocco provide the only land borders between Africa and the EU.
Spanish Prime Minister Mariano Rajoy has appealed for help from Europe to deal with illegal immigration.
He says Brussels should step up support for countries like Spain that have territory on the EU’s borders.
