Mexico City: Eleven years after her son vanished, Delfina de la Cruz vented frustration at the unsolved disappearances of 43 Mexican students who were allegedly kidnapped by drug traffickers while authorities turned a blind eye.

The students from the Ayotzinapa teacher training college -- whose members have a history of political activism -- had commandeered buses to travel to a demonstration in Mexico City when they went missing on September 26, 2014.

The case is considered one of the worst human rights atrocities in Mexico, where a spiral of drug-related violence has left more than 120,000 people unaccounted for.

In the rain, de la Cruz and the mothers of other victims led a massive protest march in Mexico City on Friday to mark the anniversary.

"We are back where we started," she said. "I want to see my son, (know) what happened, where he is, if he is no longer there."
