Unesco's director-general has urged the Mexican authorities to investigate the murder of citizen journalist Maria del Rosario Fuentes.
Irina Bokova issued a statement about the "brave woman" saying: "It is important that the authorities do all in their power to bring those responsible for the killing of Ms Fuentes Rubio to justice, as this could help strengthen media independence and the right of information."
Fuentes Rubio, a physician, was abducted on 15 October after leaving work at a clinic in Reynosa, a city in the northeastern state of Tamaulipas, which has long been a battleground for rival drug cartels.
The following day, a photograph of her dead body appeared on her social media account.
Fuentes Rubio used social networks to circumvent organised crime groups' efforts to suppress information about their activities.
She was also a frequent contributor to a blog, Valor por Tamaulipas (Courage for Tamaulipas), where she encouraged crime victims to report offenders to the police.
