The Tunisian coastguard has recovered the bodies of 21 migrants after their boat sank off the port of Sfax.
Fifty people were saved in a rescue operation carried out on Sunday.
It was the second such disaster in Tunisian waters in two days.
At least 43 people drowned on Saturday when their boat ran into trouble near the southern city of Zarzis.
Eighty-four people aboard the vessel were rescued.
They’d come from countries including Egypt, Sudan and Bangladesh, and they’d set off from Libya in the hope of reaching Europe.
