MIGRATION
Authorities found 51 migrants dead of heat exhaustion, dehydration and related causes in the back of an airless lorry abandoned on an interstate highway near San Antonio, Texas, on Monday. Most of the migrants – men, women and children – were from Mexico and Central America. It is the deadliest single human smuggling incident in U.S. history, coming amid a surge of attempted border crossings. Crisis Group expert Tiziano Breda says the horrific incident illustrates the impossibility of suppressing northward migration in the Americas when Mexicans, Central Americans and others are willing to take such risks to escape increasing privation and violent crime in their home countries.
