SAN SALVADOR/TEGUCIGALPA (Reuters) - At least 150 Salvadoran migrants departed in a group for the United States on Wednesday, the latest in a string of such 'caravans' that U.S. President Donald Trump has used to build his case for a wall along the U.S.-Mexican border.

The group, organised through social media, is following in the wake of a larger caravan that departed from Honduras this week.
