Charlie Kirk, a close ally of former U.S. President Donald Trump, was shot dead Wednesday during a student event at the University of Utah. The 31-year-old activist was addressing students when a sniper opened fire from a nearby rooftop. He was rushed to hospital but later died. Just seconds before the shooting, Kirk had been asked about gun violence in the U.S. A suspect was initially detained but later released. President Biden extended condolences, calling the killing a “tragedy.”
