The bodies of 35 migrants have been recovered off Tunisia's southern coast, the country's defence ministry said Sunday, revising upwards an earlier government death toll.
As of 1:00 pm (1200 GMT), "35 bodies were recovered and 68 migrants rescued," said Rachid Bouhoula, a spokesman for the ministry.
The interior ministry reported a distress call on Saturday night at 10:45 pm from "a fishing boat about to sink" with migrants on board.
Tunisians and seven foreigners were among the survivors, including nationals from Ivory Coast, Mali, Morocco and Cameroon, said the defence ministry spokesman.
"The coastguard and the navy continue their search with the support of a military plane," the interior ministry said in a statement.
"Units of the Sfax Marine Guard and the Navy went to the boat which was five nautical miles from Kerkennah island and 16 nautical miles from the city of Sfax," the ministry added.
Tunisians and migrants regularly try to cross the Mediterranean to seek a better future in Europe, but departures peaked last September.
According to non-governmental organisations, the uptick reflected frustration among young people hard hit by unemployment.
In October, a collision between a migrant boat and a Tunisian military ship left at least 44 dead, in what Prime Minister Youssef Chahed called a "national disaster".
The fishing boat was found five nautical miles from Kerkennah island (pictured) and 16 nautical miles from the city of Sfax, the defence ministry said
