Demonstrators are protesting Mexican President Andres Manuel Lopez Obrador's infrastructure projects, including a thermoelectric plant in Morelos state and the "Mayan Train" on the Yucatan peninsula. The protest brought together unions, environmentalists, students and representatives of Mexico's indigenous peoples, a mix that would seem a natural base for Lopez Obrador, but which has become among his most vocal critics.
