Central American migrants run for a parked train during their journey toward the US-Mexico border, in Ixtepec, Oaxaca state, Mexico, Tuesday, April 23, 2019. The once large caravan of about 3,000 people was essentially broken up by an immigration raid on Monday, as migrants fled into the hills, took refuge at shelters and churches or hopped passing freight trains.
