MEXICO-US-MIGRANTS-CARAVAN

Central American migrants taking part in a caravan called "Migrant Viacrucis" towards the United States hold a banner reading "Emigrant Viacrucis 2018. We are all America. No to discrimination" as they march to protest against US President Donald Trump's policies in Matias Romero, Oaxaca State, Mexico, on April 3, 2018. The hundreds of Central Americans in the "Way of the Cross" migrant caravan have infuriated Trump, but they are not moving very fast -- if at all -- and remain far from the US border. As Trump vowed Tuesday to send troops to secure the southern US border, the caravan was camped out for the third straight day in the town of Matias Romero, in southern Mexico, more than 3,000 kilometers (1,800 miles) from the United States. / AFP PHOTO / VICTORIA RAZO (Photo credit should read VICTORIA RAZO/AFP via Getty Images)
