In a separate incident on the same day, more than 60 people were reported missing, with 26 of them feared to be children, Médecins Sans Frontières (MSF) said.
The boats were carrying migrants who had set off from Libya and Turkey, UN agencies said.
Survivors of the shipwreck near Lampedusa were handed over to the Italian coastguard and taken ashore on Monday morning, while the deceased were being towed to the island, according to RESQSHIP.
