Navy Commander Aldo Dolfino told Sky TG24 today that migrants had been evacuated from eight life rafts and one boat, which alone carried some 500 migrants.
Italy's top security official told Parliament last week that 20,500 migrants had arrived so far this year, a huge increase over the 2,500 in the same period of 2013. Most boats come from Libya carrying migrants from Africa.
Save the Children has noted an increase in the number of minors, many traveling alone.
