One day after reaching their area of operation, the German organization Sea-Watch rescued more than 60 people in the Mediterranean from distress.
Sea-Watch wrote on Twitter on Sunday that there were many children among them.
The people on board would receive medical care.
Three hours later, Sea-Watch reported a second rescue operation in which 54 people were rescued from a rubber dinghy.
According to the private sea rescuers, the area of operation of the "Sea-Watch 3" is off the coast of Libya.
The ship had brought more than 250 rescued boat migrants to Trapani in Sicily at the beginning of August.
In addition, according to reports from the Italian news agency Ansa, 49 migrants arrived on Sardinia's coasts in several boats on Sunday.
Another 31 migrants reached the Italian island of Lampedusa and 41 - all Tunisians - went ashore in Sicily.
People mostly try to get to the EU from the coasts of Tunisia or Libya across the Mediterranean.
You are on the run or are hoping for a better life there.
Again and again there are accidents with fatalities on the dangerous crossings.
Sometimes the coast guards of the North African countries pick up the people and bring them back.
According to the International Organization for Migration (IOM), around 1,400 migrants have died in the dangerous crossing over the Mediterranean since the beginning of the year.
According to official figures, there were more than 1200 fatalities last year.
However, experts assume a high number of unreported cases.
