Irina Bokova, the director-general of UNESCO, condemned Castillo's slaying: "This crime is an attack on the basic human right of journalists and citizens to speak their mind and hold free debates about issues that concern them.
I urge the authorities to investigate this killing and bring its culprits to justice.”[5] Despite the pressure applied by UNESCO and NGOs, no progress has been made in the case.
[7] His murder was followed months later by the killing of another Peruvian journalist Pedro Alfonso Flores Silva, who worked for Channel 6 in Chimbote, on 8 September.
[8] The third broadcast host José Oquendo Reyes, of both Radio Alas Peruanas and BTV Canal 45, was killed 14 September in Pueblo Nuevo.
The fact that he was killed on World Press Freedom Day adds to the hurt and the suffering from this tragedy but should also strengthen our resolve to stop violence against journalists".
