Mexico City, March 9 (teleSUR-RHC)-- The mothers of Ayotzinapa's 43 missing students headed an International Women's Day march on Sunday in Mexico City.

The march was proceeded by an event late Saturday, entitled “Women and Ayotzinapa,” during which mothers of the students spoke about their experiences and vowed to continue their search.

“We want to make it very clear to the federal government that we are not afraid. That is why we ask (people) to continue uniting and organizing, because they (the government) know where our sons and daughters are, and if they have not found them it's because they have not wanted to,” said Carmen Cruz, the mother of one of the missing students.

The mothers also responded to the removal of Attorney General Jesus Murillo Karam, a decision made last week. This will not stop the Ayotzinapa movement, said one of the mothers.

Murillo Karam became infamous after rejecting further questions about the case during a press conference in November last year, alleging he was too tired to continue. It was the same conference in which he announced that the students had been killed by drug traffickers, a claim disputed by the parents.

The now former Attorney General also threatened to close the investigation on the case, despite not having definite proof of the death of the students.
