The death toll from the capsize off Senegal of a boat carrying migrants rose to 39 following the discovery of more bodies on Monday, the country’s emergency services said.

The boat, which left Saint-Louis in northern Senegal and was headed to the Spanish coast, overturned on Sunday, offshore from the town of Kébémer, north of the capital Dakar.

The Ministry of Interior said Sunday at least 21 people had died and rescuers were looking for possible survivors.

It did not say how many people were on the boat, but several passengers are still believed to be missing.

Only one passenger was rescued alive.

The boat was following a well-traveled migration route for thousands of young Senegalese seeking better economic conditions.

They travel on uncovered wooden canoes for around 800 miles on the Atlantic Ocean to reach Europe.

Young people face high unemployment and poverty as the country struggles with an economic crisis.

Senegal’s President Bassirou Diomaye Faye offered condolences and vowed to clamp down on networks behind the dangerous crossings.
