Attendees at the campus event where US conservative activist Charlie Kirk was fatally shot on Wednesday have described mass panic after a shot was heard. Kirk, 31, was killed after he was hit in the neck by a single bullet, which law enforcement believes came from a shooter on the roof of a nearby building. The influencer and close Donald Trump ally had been speaking to about 3,000 people on his American Comeback Tour at Utah Valley University. Videos on social media show Kirk talked about gun violence moments before he was shot.

One eyewitness told BBC News: Me and my buddies were having a good time just listening to what was going on and we just saw it, heard a loud shout, loud bang and then I saw his body actually in slow motion kind of fall over. Another witness, Danielle, expressed her horror at the scene: It was horrible. All I hear is screaming and I see people running and I'm like, 'it's not safe to run.' The chaotic aftermath saw students and attendees desperately searching for safety amid cries and confusion. Security arrangements at the event are under scrutiny as discussions about gun violence in America continue.
