Marking World Press Freedom day on May 3, the Turin daily is publishing a special edition dominated by a photo of its war correspondent Domenico Quirico, who has been missing in Syria for 3 weeks, and the yellow ribbon symbolising the campaign for his release.

“An international effort to make the the regimes limiting press freedom feel the pressure of public opinion may make a difference,” writes editor in chief Mario Calabresi in his editorial.

In a guest column, Reporters sans frontiéres Secretary General Christophe Deloire celebrates “our heroes”, the journalists who risk their freedom and life to “defend our right to keep our eyes open.” Among them is Mazen Darwish, the jailed head of the Syrian media centre who was awarded the organisation’s press freedom prize in 2012.
