The National Guard on Thursday said Tunisia’s coast guard has recovered the bodies of 27 African migrants.
The coast guard said the two boats were attempting to cross the Mediterranean after it sank off the coast.
The boats sank in waters off the city of Sfax, a departure point often used by African migrants.
Last month, Tunisia’s coast guard recovered the bodies of about 30 other migrants in two separate incidents, after their boat sank while they were sailing towards Europe.
The National Guard added that the Coast Guard rescued 87 people who were on the same two boats that sank off Sfax.
Tunisia is grappling with an unprecedented migration crisis and has replaced Libya as the major departure point for both Tunisians and people from elsewhere in Africa seeking a better life in Europe.
