A gunman shot and killed three people and wounded more than a dozen others outside a bar in a busy nightlife district near the University of Texas at Austin before police fatally shot him. The FBI says it’s investigating the assault early Sunday as a potential act of terrorism, coming after the U.S. and Israel launched an attack on Iran. The suspect was wearing clothes with an Iranian flag design and the words “Property of Allah.” One student who had spent his evening at the bar said it was “full of college students” who were “enjoying their nights.”
