Mexico has erupted into a series of demonstrations since 43 student teachers were abducted in Iguala, Guerrero, in September. After initially claiming that the missing had been found in a mass grave, the Mexican government now says the 43 were taken by municipal police, killed by a local cartel, and their bodies burned.



The families of the missing, however, refuse to believe the government's story, and insist that the 43 are alive. Ahead of the latest anti-government march on Saturday 6 December, relatives of the student-teachers tell Adam Gabbatt that they will not rest until their loved ones are returned.
