A number of charred corpses found in mass graves in southwest Mexico are believed to be those of dozens of missing students.
The youths clashed with authorities during protests in the volatile state of Guerrero on the night of September 26.
It is alleged that police conspired with gang members to have the young people killed.
Local authorities are investigating the claims.
The Attorney General for Guerrero is Inaky Blanco: “It would be irresponsible of me, to say the find is connected with the missing students. With the information we have we can establish the location of the graves and we know that there are human remains. I reiterate, we have to wait and see what the forensic officers discover.”
As many as 29 suspects have been identified, with 26 taken into custody including Felipe Flores, head of the region’s security service.
Prosecutors claim that two gang members have admitted killing 17 of the 43 missing students.
The students were marking the anniversary of the 1968 massacre of 300 undergraduates by the Mexican army.
