Rabbi Schlomo Hofmeister told London's LBC radio he was living in the compound of the synagogue. 'Upon hearing shots, we looked down [from] the windows and saw the gunmen shooting at the guests of the various bars and pubs,' he said. 'The gunmen were running around and shooting at least 100 rounds or even more in front of our building.' Videos circulated on social media of a gunman running down a cobblestone street, shooting and shouting. Jewish community leader Oskar Deutsch said on Twitter that it was not clear whether the Vienna synagogue and adjoining offices had been the target of an attack, and said they were closed at the time. Yaakov Hagoel, Chairman of the World Zionist Organization, issued a statement Monday saying, 'I spoke recently with the Chief Rabbi of Vienna...it remains unclear if there were casualties from the Jewish community...we were required to close at this time all Jewish institutions, including synagogues and community buildings. We are of course hoping that there are no casualties at all. We will continue follow updates on the attack.' Dr. Shimon Samuels, Director for International Relations of the Simon Wiesenthal Centre denounced the attack, saying that “the Centre regards Vienna as the home-base of its mentor, Simon Wiesenthal, who was there targeted several times including a bombing. We stand in solidarity with the families of the civilian victims and police casualties, with the Viennese Jewish community and with the current Austrian government as a true friend of Israel. We also commend the police force for their rapid response.” The Conference of Presidents condemned the apparent terror attack in Vienna, denouncing the 'attack that was carried out across multiple locations in Vienna, Austria this evening.' 'We stand in solidarity with the Austrian people as this tragedy unfolds. The purveyors of terrorism are despicable and cowardly; their murderous attacks against unarmed civilians will never succeed in crushing the freedom and liberty that they abhor. Our thoughts and prayers are with the victims of this act of terror. The perpetrators must be brought to justice.'
