At least 20 African migrants were missing on Saturday after their boat sank off Tunisia as they tried to cross the Mediterranean to Italy, a judicial official told Reuters.
The coast guard rescued 17 others off southern city of Sfax from the same boat, two of whom are in critical condition, Faouzi Masmousdi, the Sfax court judge said.
