The organisations of Doctors Without Borders (MSF) and ResQ, on Monday reported that more than 200 boat migrants had been rescued in the central Mediterranean Sea in several operations.
MSF announced that the crew of the Geo Barents vessel took almost 190 people on board where the migrants had been on an overcrowded wooden boat.
The report said there was lack of oxygen below deck.
On Sunday, the volunteers of the private Italian organisation ResQ saved dozens of people in several operations.
Among the refugees were many women and minors.
The crew of the ResQ People vessel had about 165 people on board after the rescues, and were demanding a safe harbour to let the people go ashore.
Most migrants set off from the coasts of Libya and Tunisia to reach the European Union via the Mediterranean.
According to Interior Ministry, Italy saw a doubling of the number of migrants reaching the Mediterranean country in boats within a year.
Between August 1, 2020, and July 31, 2021, authorities registered a total of 49,280 people arriving on Italian shores.
This represented an increase of 128 per cent year-on-year from 21,616.
A total of 147 traffickers were arrested, representing an increase of 25 per cent.
