Govt pressured for answers on missing students, one year later

Tens of thousands marched in Mexico City on Saturday to demand answers on last year's disappearances of 43 students, piling new pressure on President Enrique Pena Nieto to clear up a case that has battered his image.

A year to the day since 43 trainee teachers went missing in the southwestern city of Iguala after clashes with local police, protesters held up banners ridiculing Pena Nieto's response to the crisis and accusing him of trying to draw a line under it.

Simmering anger over the disappearances, which exposed deep flaws in Mexico's justice system, has dashed any hopes the president harbored of turning the spotlight away from violence and lawlessness that have plagued the country for years.
