A Salvadoran girl waves her national flag as Central American migrants traveling with the annual Stations of the Cross caravan march to call for migrants' rights and protest the policies of U.S. President Donald Trump and Honduran President Juan Orlando Hernandez, in Matias Romero, Oaxaca state, Mexico, Tuesday, April 3, 2018. Bogged down by logistical problems, large numbers of children and fears about people getting sick, the caravan was always meant to draw attention to the plight of migrants and was never equipped to march all the way to the U.S. border.
