MEXICO CITY — Former Mexican President Luis Echeverria, blamed for some of Mexico's worst political killings of the 20th century, has died at the age of 100, current President Andrés Manuel López Obrador confirmed Saturday.

In his Twitter account, López Obrador sent condolences to Echeverria's family and friends "in the name of the government of Mexico," but did not express any personal sadness about the death. López Obrador did not provide a cause of death for Echeverria, who governed Mexico from 1970 to 1976.
