It said the migrants, mostly from sub-Saharan Africa, were rescued between Tuesday and Friday when their makeshift boats, including rubber dinghies and kayaks, ran into difficulty.

Last week Morocco's navy reportedly rescued 344 migrants in the Mediterranean and the Atlantic.

Migrants in the North African country often try to reach the Spanish mainland via the Mediterranean, while in the Atlantic Ocean they make for Spain's Canary Islands.

A total of 2,087 migrants died trying to reach Spain by sea during the first six months of 2021, roughly the same number as during all of last year, a migrant rights group said earlier this month.

Spanish interior ministry figures show that between January 1 and June 30, a total of 12,622 migrants arrived in Spain by sea, almost twice as many as those who made the crossings last year.
