A serious accident occurred off the coast of Libya.
At least 74 people drowned in the sinking of a boat carrying refugees.
The International Organization for Migration (IOM) announced on Thursday.
More than 120 people are said to have been on board the boat, including children.
47 survivors were brought ashore by the coast guard and fishermen, the IOM said.
31 bodies were recovered.
The search for victims continues.
Time and again, migrants are killed in accidents in the Mediterranean.
The IOM said that in the past two days alone, two boats capsized and at least 19 people drowned.
On Wednesday, private Spanish rescuers rescued more than 110 migrants from Libya from distress.
Shortly after the rescue from the Mediterranean, a six-month-old refugee baby died on the ship "Open Arms", according to the helpers.
As Open Arms announced on Thursday, the team pulled five dead out of the water during the operation.
With the baby, the death toll rose to six.
Many people continue to set off in small boats in the North African countries of Tunisia and Libya to get to Europe.
Several boats with hundreds of people have landed on the island of Lampedusa in the past few days.
According to official figures, a total of almost 31,000 migrants have arrived in Italy so far in 2020.
In 2019 there were just under 10,000 people in the same period.
