Hundreds of African males forced their way into the Spanish enclave of Melilla on Thursday morning, according to reports.
More than 230 illegal aliens successfully reached European soil in the latest siege of the autonomous city, one of two controlled by Spain on the African continent.
Video footage of the blitz shot from the Moroccan side of the border was shared on social media.
Men using hooks and wearing shoes fitted with screws scaled the border fence en masse, overwhelming Spanish security forces.
The hand-made hooks are used by immigrants to help them climb the fences, which are six meters high, especially since a few years ago the Interior Ministry reinforced the perimeter with anti-trap nets.
At least 238 sub-Saharan Africans entered Melilla, but some sources indicate the number could be much higher.
