More than 60 people are feared dead after a boat carrying mostly Senegalese migrants capsized off the coast of Cape Verde in the Atlantic Ocean.

The boat left Senegal on July 10 with 101 passengers on board, and 38 people were rescued on Tuesday, Senegal’s foreign ministry said in a statement late on Tuesday.

It was not immediately clear when the incident occurred.

The survivors were on the Cape Verde island of Sal, where Senegal is liaising with authorities for their repatriation, the ministry said. One of the survivors was from Guinea-Bissau.

The Atlantic migration route from the coast of West Africa to the Canary Islands, typically used by African migrants trying to reach Spain, is one of the world’s deadliest. Summer is its busiest period.

“Safe and regular pathways to migration are sorely lacking, which is what gives room to smugglers and traffickers to put people on these deadly journeys,” said International Organisation for Migration spokeswoman Safa Msehli.

At least 559 people died attempting to reach the Canary Islands in 2022, while 126 people died or went missing on the same route in the first six months of this year with 15 shipwrecks recorded, according to the IOM.
