A child stands beside a wire fence in Kharaz refugee camp holding a homemade toy wooden rifle. The isolated camp, housing roughly 15,000 people, half of which are children, sits in the desert 136 kilometres from Aden. The United Nations Refugee Agency (UNHCR) has raised concerns over the record numbers of Ethiopians and Somalis flocking to Yemen, despite the deteriorating security situation there. In 2011 103,000 migrants crossed the Gulf of Aden and Red Sea. Most arrive dehydrated and malnourished and face physical and sexual attacks. They are regularly robbed and attacked by smugglers and traffickers.
