Mexico: Families search hills for missing relatives
The disappearance of 43 students in late September has provoked a political crisis in Mexico, but the case has also thrown new light on the estimated 26,000 people who have gone missing across the country in the last decade.
Several mass graves have been found during the search for the students, many the result of drug-related violence.
A father of three kidnapped children told the BBC: 'The students of Iguala was the tip of the iceberg [which] revealed all this'.
Juan Carlos Perez joined one group searching for their missing family members in the Mexican hills.
