ITALY-IMMIGRATION-SHIPWRECK

Migrants walk at the Cara Mineo, a hosting centre for asylum seekers, where about 3,200 migrants from North Africa, Ivory Coast, Pakistan, Syria, Afghanistan and other countries are staying in Mineo in the the province of Catania in Sicily on April 21, 2015, three days after a migrant boat capsized in the Mediterranean's deadliest disaster in decades. Only 28 people, including the two arrested men, survived the disaster on April 19, 2015 in which 800 people are feared to have drowned. Some of the survivors, who hailed from Mali, Gambia, Senegal, Somalia, Eritrea and Bangladesh, were recovering at the holding Cara Mineo centre.
