Prosecutors are using harsh anti-smuggling laws to jail people who have no connection to criminal offences, say migrants’ lawyers

Former law student Samuel, 19, fled his home town of Geneina shortly after it was ransacked during one of the worst massacres of Sudan’s brutal civil war, which has killed tens of thousands and displaced more than 13 million people.

After making it overland to Libya, Samuel spent two days crossing the Mediterranean in June before being rescued by a cargo ship and escorted by the Greek coastguard to Crete.
