The number of immigrants who arrived through Italy's coastline fell by more than 75% period from 1 August 2017 to 31 July 2018, the Italian Interior Ministry said.
Libya is the most common starting point for migrants seeking to reach Europe by sea. More than 600,000 people have crossed the Mediterranean into Italy in the last four years, most of them from Libya.
European forces have also pressed for a reduction in flow to Libya from the south and the International Organization for Migration (IOM) has repatriated 25,000 immigrants from Libya since the beginning of last year.
According to another report released by the International Organization on Migration, the number of immigrants this year has declined to 19,231 from 97,295.
The Italian report, says that "65% of immigrants who landed on the Italian coast during the year, arrivedfrom Libya,15% from Tunisia, 3.5% from Turkey, and 2% from Algeria, Greece, Egypt and 0.5% from Montenegro."
As for the nationalities of expatriates, "20% were Tunisians, 11% Eritreans, 7% Nigerians, 6% Sudanese, 6% of Ivorians, 5% Algerians, 4% Moroccans and Guineans."
The report noted that "6833 repatriation operations were carried out," a slightly higher than the 6378 recorded the previous year.
The issue of illegal immigration has been exacerbated since 2011, as smugglers take advantage of the chaos that prevails in Libya to transport tens of thousands of migrants each year towards Europe.
