An independent investigation into the disappearance of 43 Mexican students nearly a year ago has rejected the government's account of events.

The government investigation said the bodies were burned at a rubbish dump hours after the students went missing.

But the Inter-American Commission on Human Rights says it has found no evidence to support claims that the bodies were incinerated.

The Mexican government is sending forensic experts to the area.

The move was announced by Attorney General Arely Gomez Shortly after the IACHR report was published.

Relatives have always rejected the official investigation.

They accused the authorities of covering up the alleged involvement of high-ranking officials and possibly the army in the killings.

The case shocked Mexico and led to weeks of protests against official impunity and the government of President Enrique Pena Nieto.
