The 14 bodies were recovered overnight in the Mediterranean Sea off Tunisia’s central Sfax region, National Guard spokesperson Houssameddine Jbabli told the Associated Press. The National Guard said the migrants were from sub-Saharan Africa but did not release their nationalities.

On the same night, coast guard vessels thwarted 14 other boats carrying a total of 435 migrants attempting a similar journey from central and southern regions of Tunisia, Jbabli said.

People fleeing conflict or poverty routinely take boats from Tunisian shores toward Europe, even though the central Mediterranean is the most dangerous migration route in the world, according to the International Organization for Migration. Many are from sub-Saharan Africa, but Tunisians and people of other nationalities are also among those risking the journey.

Tunisian authorities have stepped up arrests of Africans without residency papers in recent weeks after President Kais Saied lashed out at sub-Saharan migrants. The comments fanned a surge in racist incidents targeting Black Africans in Tunisia.
