Spain was searching for almost 143 people missing on five migrant boats en route to the Canary Islands in the Atlantic Ocean, according to Spain's maritime rescue service on Tuesday.
Authorities were alerted about the missing boats on Monday afternoon.
A Civil Guard plane was searching for the boats near the islands of Lanzarote and Fuerteventura, off the northwest coast of Africa, the service said.
Helena Maleno, of the human rights group Walking Borders, told The Associated Press that the migrants are believed to have departed from the northwest coast of Africa between Friday and Saturday. They include women and children.
Although the total number of sea crossings to Spain decreased by more than 50% in 2019, arrivals via the dangerous Atlantic route to the Canary Islands doubled.
According to the International Organization for Migration at least 210 people died on that route last year.
