About 171,000 refugees tried to cross the 250 mile stretch of ocean in rickety boats from Libyan ports into Italy in 2014, according to Frontex, the EU border agency . Refugees from Syria, Libya, Tunisia, and Eritrea are fleeing their homelands. A smuggling trade is carried out by tribes in Libya for these refugees, with one tribe making $60,000 a week. The tribes then use the money to buy weapons in the Libyan civil war. Migrant deaths at sea and inadequate rescue efforts are leading to a humanitarian crisis for Italy and the EU.
