At least 29 migrants have died after two boats sank off Tunisia’s coast within hours of each other, officials say.
Officials added that the sub-Saharan migrants were trying to cross the Mediterranean to reach Italy.
It is the latest in a string of migrant boat capsizes off Tunisia’s coast in the last few days, with five others sinking in the past four days.
This comes after Tunisia launched a campaign against undocumented African migrants.
Meanwhile, Italian officials on the island of Lampedusa say they are overwhelmed, after a record 2,500 migrants arrived in the last 24 hours.
The Italian far-right Prime Minister, Giorgia Meloni, has warned Europe risks seeing a huge wave of refugees arriving on its shores.
Tunisia has become a hub for migrants who wish to make it to Europe, with UN figures showing at least 12,000 migrants who landed on Italy’s shores this year left from Tunisia.
The Tunisia coast guard say they are taking steps to stop the migrant crossings, having halted around 80 vessels headed for Europe in the past four days.
In a controversial speech last month, Tunisia’s president accused sub-Saharan African migrants living in the country of causing a crime wave and described them as a demographic threat.
Kais Saied’s comments were widely criticised by the African Union and denounced as “racist hate speech” by human rights groups.
These comments have left some sub-Saharan Africans in Tunisia living in fear, with some saying they have seen an increase in racist incidents.
Tunisia’s economy is in a poor state, and is facing crisis after negotiations with the the International Monetary Fund (IMF) stalled.
The US Secretary of State Antony Blinken has also warned that Tunisia urgently needs to reach a bailout deal with the IMF.
