The mothers of the 43 students, from a teachers’ college in Ayotzinapa, a town in the southern state of Guerrero, who went missing in September 2014, led the march in the capital on Wednesday.
The mothers seized the special occasion to pressure the authorities to do more to locate their missing loved ones.
More than two and a half years has passed since the 43 students disappeared. Their fate remains unknown.
During the protest march, the mothers chanted “May 10 is not for celebrating. It’s for fighting and protesting.”
“Here we are, mothers looking for our children and raising our voice for all those who are missing from our homes,” said Araceli Salcedo, the mother of a girl who has also gone missing in drug-related violence.
In September 2014, 43 student-teachers disappeared after police stopped them on their way to attend a demonstration in the southwestern city of Iguala, in Guerrero State. Reports say clashes broke out between police and the students, who were never seen again.
Six months later, Mexico’s government claimed corrupt police officers had handed the students to local drug henchmen, who then incinerated their bodies at a garbage dump. However, investigations by independent forensic experts later discredited the government’s claims and the case remains open to this day.
According to government sources, at least 28,000 people in Mexico have gone missing in drug-related incidents.
