I just received this from the U.S. Embassy in Vienna
“ According to Vienna police officials, both left-wing Antifa groups and right-wing Identitarian groups are calling on supporters in Austria and around Europe to rally and demonstrate in the 1St District on Saturday, July 20th. Demonstrators will start to gather in the late morning/early afternoon and will commence marching at 3:00 PM. Affected protest and staging areas include Neuer Markt, Am Hof, Freyung, Albertina-Helmut Zilk Platz, and Morzinplatz in the 1st District. The possibility of confrontation and physical altercations between these groups and with police does exist. As such, there will be a large police presence in the 1st District. Traffic delays, disruptions and road closures are expected. U.S. citizens are advised to avoid the affected areas if possible and not engage with demonstrators‘
