"Violence and insecurity are so bad that other war-torn countries have become sites of refuge."
In 2015, nearly 100,000 Ethiopians and Somalis traveled by boat to Yemen, one of the world's most dangerous countries. Last year, nearly 5,000 citizens of Congo, which is fighting powerful rebel groups, were seeking refuge in the Central African Republic, itself torn apart by civil war. And yet 10,000 Burundians have fled their country's own growing civil unrest for Congo. Thousands of Nigerians escaping the extremist Islamist group Boko Haram have gone to Chad, where different strains of that same insurgency conduct frequent deadly attacks.
Developing countries have long taken in a disproportionate number of the world's refugees — roughly 80 percent, according to the United Nations. But even for migration experts and relief workers, the willingness of refugees to leave one war for another is shocking. It's also proving an enormous challenge for humanitarian agencies, which are already overstretched and often not equipped to welcome refugees in countries that are still racked by conflict.
