A demonstration in Frankfurt against Operation Protective Edge erupted into violence, with protesters tossing stones at the police.According to the Frankfurter Rundschau paper, about 2,500 protesters appeared in downtown Frankfurt, screaming “God is great,” and slogans such as “freedom for Palestine” and “children-murderer Israel.”Eight police officers were injured. One sign at the rally was titled, “You Jews are Beasts.”German media reported that after the protests, groups sought to locate Jewish institutions. The Frankfurt police said Jewish institutions would be protected. It is unclear if the goal was to attack said institutions.According to the Rundschau, student organization Left-SDS, Islamists and some members of the Neo-Nazi group National Socialists Rhein-Main attended the anti-Israel protest. Flags from Turkey, Iraq, Saudi Arabia and Hamas were on display at the protest. Banners compared Prime Minister Netanyahu with Adolf Hitler.Supporters of Assad’s regime were also present at the protest.In a bizarre act of cooperation, German journalist and publicist Thomas von der Osten-Sacken reported on the website of the weekly Jungle World that Frankfurt’s police allowed the demonstrators to use a police vehicle and loudspeaker to blast anti-Israeli slogans. According to a police statement, the authorities allowed the use of their equipment in order to deescalate the situation. The Jungle World article sarcastically titled its account, “The Police, Friend and Helper.”
