Via Der Standard:
Several hundred people marched this past Saturday in Vienna in support of wiping out Israel as part of Al-Quds Day. The protesters shouted "Israel child-killers" and "Zionism is fascism". Israel was also accused of supporting the Islamic State.
Before the protest started, a woman shouted at counter-demonstrators that they're "child-killers" and "America's dogs". She also said "Thank you to Hitler that he killed the Jews" , a sentiment she repeated several times in various ways. In the clip she's saying it's "a wonder that Hitler didn't kill all of you".
