Latest incident comes amid sharp rise in numbers trying to leave crisis-hit north African country
At least 20 people were missing on Saturday after their boat sank off Tunisia as they tried to cross the Mediterranean to Italy, amid a sharp rise in boats setting off from the north African country.
The coastguard rescued 17 other people from the same boat off the southern city of Sfax, two of whom were in critical condition, said a local judge, Faouzi Masmousdi.
