One of the latest events in Europe to be hit with accusations of anti-Semitism, the Vienna Festival kicks off on Friday, with its new director, Milo Rau, urging that places of culture be kept free of the “antagonism” of the Israel-Hamas conflict while still tackling difficult issues, AFP reports.

As the conflict in Gaza sharply polarises opinion, “we must be inflexible” in defending the free exchange of ideas and opinions, the acclaimed Swiss director told AFP in an interview this week.

“I’m not going to take a step aside… If we let the antagonism of the war and of our society seep into our cultural and academic institutions, we will have completely lost,” said the 47-year-old, who will inaugurate the Wiener Festwochen, a festival of theatre, concerts, opera, film and lectures that runs until June 23 in the Austrian capital and that has taken on a more political turn under his tenure.

The Swiss director has made his name as a provocateur, whether travelling to Moscow to stage a re-enactment of the trial of Russian protest punk band Pussy Riot, using children to play out the story of notorious Belgian paedophile Marc Dutroux, or trying to recruit Islamic State jihadists as actors.
