Turmoil and Protests Shake Latin America

LIMA, Peru—This country has had six presidents in five years, the latest taking power last month and igniting protests that have cost 42 lives and paralyzed many of Peru’s highland cities.

In Mexico, President Andrés Manuel López Obrador has taken measures that undermine the country’s independent electoral agency, while thousands of supporters of former Brazilian President Jair Bolsonaro, many of them who said his opponent had rigged the October presidential election, last week ransacked the country’s presidential palace, the Congress and the Supreme Court.
