Mexican authorities say that they have found four more mass graves near the site in Iguala, Guerrero, where 43 students went missing in September.

The Mexican newspaper El Universal reports that Jesús Murillo Karam, with the attorney general's office, said that they arrested four people, who led them to the graves.

Of course, the big question here is whether the bodies that have so far been found in the five other graves discovered earlier, belong to the college students. Authorities say they are still working to identify them.

BBC Mundo reports that the bodies inside the new mass graves were also incinerated. Their correspondent in Mexico, Juan Carlos Pérez Salazar, says the graves are about a 20-minute walking distance from the ones found previously.
