About 50 migrants were missing after their boat overturned some 100 kilometers (60 miles) south of Spain's Canary Island of El Hierro in the Atlantic Ocean, Spanish media reported Monday.
The national marine rescue service said one of its helicopters rescued nine people who were found clinging to the boat Monday morning following a warning call from a merchant vessel in the area.
State news agency Efe said that once transferred to El Hierro airport, the rescued migrants reported that 60 of them had set sail nine days ago and that the open-topped wooden boat ran into problems Saturday.
The rescue service was unable to say how many people may have been on the boat and no one was available to comment at Civil Guard police offices in the Canary Island capital of Santa Cruz de Tenerife.
Efe said the migrants were of sub-Saharan origin. There were no details on which country they had sailed from.
Tens of thousands of migrants from sub-Saharan countries fleeing poverty, conflict and instability in West Africa try to reach Spain each year by boat. Most go in large open vessels to the Canary Islands in the Atlantic, while others from Morocco, Algeria and Middle Eastern countries try to cross the Mediterranean Sea and Atlantic Ocean to mainland Spain. Several thousand die during the hazardous journey.
The Interior Ministry says 16,621 migrants arrived in Spain by boat between Jan. 1 and April 15, up by 11,681 in the same period last year. The vast majority arrived on the Canary Island route.
