Six people perished after three migrant ships capsized in the Mediterranean Sea, including a mother and baby.
A ship capsized on Sunday off the Kerkennah Islands in Tunisia, resulting in at least four fatalities and 51 being reported as missing.
A woman and child perished along with more than 30 people who are believed to be missing after two ships sank off the coast of Lampedusa, Italy, in a separate incident.
Italian coast guards found the bodies of the Ivory Coast woman and her infant child, who was one year old.
All those on board were from sub-Saharan Africa during the incident off the Kerkennah Islands, a judicial official told Reuters.
Officials from Tunisia reportedly reported discovering the bodies of 10 migrants on a beach close to Sfax.
The official told the AFP news agency that the 10 persons were discovered between Friday and Saturday amid a windstorm that might have capsized their boat.
According to Tunisian authorities, the port city is a well-liked entry point for immigrants looking for a better life in Europe.
The migrants were largely from sub-Saharan African nations, according to Sfax officials, who said they were trying to determine their nationalities. Sfax is only about 80 miles (130 kilometres) from Lampedusa.
The occurrences were under investigation, according to Italian authorities.
When the boats sank on Saturday, some 23 nautical miles (46 km) south-west of Lampedusa, the Italian coastguard reported that it had saved 57 people.
More than 30 people had been reported missing earlier, according to the International Organisation for Migration, the UN’s migration agency.
Firefighters and mountain rescue teams were getting ready to save 20 migrants who were stranded on a rocky section of Lampedusa’s coastline on Sunday.
After the boats were forced against the rocks by heavy winds late on Friday, the migrants have been there ever since.
The NGO Open Arms reported that it has begun disembarking 195 rescued migrants in the port of Brindisi in southern Italy after more than two days of sailing in rough weather.
The investigation’s police chief, Emanuele Ricifari, told local media that the traffickers would have been aware of the impending severe seas.
“Whoever allowed them, or forced them, to leave with this sea is an unscrupulous criminal lunatic,” Mr. Ricifari remarked.
Another 2,000 people who have arrived on the island in recent days have been rescued by Italian patrol vessels and humanitarian organisations.
Some of the migrants have received food, water, clothing, and emergency thermal blankets from the Red Cross.
