Unrest in Yemen has prompted hundreds of Somali refugees to once again risk a deadly sea crossing, this time to return to their home country, say officials and migrants. This year alone some 89 people drowned or went missing while crossing the Gulf of Aden from Somalia to Yemen. The worst single incident took place in late February when some 57 refugees died after their boat capsized, according to the UN Refugee Agency (UNHCR). Since 2008, well over 1,000 people have failed to survive the crossing.
