Photo de stock - An exhibition presenting nearly 200 front pages of the French satirical magazine Charlie Hebdo, whose Paris editors were recently killed by terrorists, was opened in Prague´s DOX gallery today, on January 28, 2015, amid security measures. On January 7, two armed Islamic radicals stormed the Paris seat of Charlie Hebdo and killed 12 people in its office, including the editor-in-chief and leading cartoonists. The weekly has been publishing caricatures of the Prophet Muhammad as well as mocking other religious and political leaders or the untouchable Tour de France cycling race. People in France and other EU countries expressed solidarity with the Charlie Hebdo editorial staff by buying its new issue and the motto Je suis Charlie has become a symbol of condemning the terrorist attacks. DOX gallery founder Leos Valka told today´s daily Hospodarske noviny (HN) that both the preparation of the exhibition and its opening for invited guests on Tuesday were kept secret.
