The Spanish authorities are searching the ocean off the Canary Islands for a boat that went missing more than a week ago carrying at least 200 African migrants.
A search plane is scouring the waters south of the Spanish islands and other ships in the area have been asked to look out for the missing vessel.
The boat sailed from Kafountine, a coastal town in southern Senegal 1,700km (around 1,000 miles) from the Canaries.
Aid workers say many children are on board.
Two smaller boats from the same area – carrying dozens of people – are also said to be missing.
