Jan Ali Razaiem said he made the long journey from his home in Afghanistan to Greece for a better future for his two sons.

Instead, he has been forced to settle for the squalor of Moria, a filthy overcrowded migrant camp on the island of Lesbos where fights over food are common, violence is rife and he is forced to share a small tent with 16 people.

"If I had known what it was like here, we wouldn't have come here; death would have been better that this," he told Reuters.
