Since January, over 85,000 migrants and asylum seekers have landed in Italy - that's a 20 percent increase on the same period last year. More and more of them are minors who arrive alone, without their family - their number is five times higher than in 2011. Our correspondents have been to Sicily, the main port of arrival for migrants on the peninsula. They met several children and teenagers from Africa who are now adjusting to a new life in Italy.
