Spain's coast guard has found 17 dead migrants on a boat off the Canary Islands, the country's local emergency services announced on Monday.
Three survivors, two men and one woman, were transferred by military helicopter to a hospital on Tenerife.
"The three had hypothermia but were otherwise in good shape," a spokeswoman for Spain's local emergency services said.
The boat was first spotted by an Air Force plane, about 265 nautical miles from El Hierro.
A spokeswoman from Spain's maritime rescue service said that all migrants on the boat were sub-Saharan Africans. It wasn't immediately clear where the migrants had come from.
Migrant arrivals in the Canary Islands increasing
About 3,400 people arrived in the Canary Islands from January 1 to March 31.
This incident follows another one south of El Hierro earlier this month. Four people were found dead in a makeshift boat with 23 migrants on board.
On Sunday, 100 migrants tried to reach the Spanish enclave of Ceuta from Morocco.
