A navy rescue plane had been searching since Monday for a makeshift boat which had set off from the northern Morocco coast not far from the Spanish enclave of Melilla. After finding it the spotters also found a second one.
All the migrants, who appeared in reasonable condition, were handed over to the Red Cross in the southeastern port of Almeria, Spain's sea rescue service said.
