Parents lead protest of probe into missing 43 students in Mexico

MEXICO CITY (Reuters) - Thousands of protesters gathered in Mexico City on Tuesday, angered by the government's handling of an investigation into 43 students who apparently were massacred in 2014 and the government's alleged treatment of international experts who have cast doubt on the official account.

The case of the 43 trainee teachers, who were abducted in September 2014 in the violent southwestern state of Guerrero, has tarnished the reputation of President Enrique Pena Nieto and highlighted the scale of human rights abuses in Mexico.
