CIUDAD HIDALGO, Mexico—Hundreds of Central American migrants waded across the Suchiate River into southern Mexico on Monday in a new test of President Donald Trump’s Central America strategy to keep them away from the U.S. border.
Some scuffled with national guardsmen on the riverbank while others slipped through Mexican lines and trudged off on a rural highway in small groups. Immigration authorities nabbed more there and chased others into the brush.
