French President Emmanuel Macron vowed Europe would not bow to terrorists following the shootings in Vienna on Monday in which at least two people including one attacker died and several more were injured. "We French share the shock and sorrow of the Austrian people following the attack in Vienna," Macron tweeted in both French and German. "After France, it is a friendly nation that has been attacked. This is our Europe. Our enemies must know who they're dealing with. We will concede nothing." cs/fjb/spm/tgb
