India, Sept. 21 -- Assassinated US activist Charlie Kirk's public memorial service will be held in Arizona on Sunday morning. Kirk, a conservative leader and a key ally of President Donald Trump, was shot dead at a public rally in Utah last week.

Security has been beefed up around the venue where the memorial service is likely to be attended by more than 100,000 people. "Expect TSA-level screening," Kirk's NGO Turning Point USA (TPUSA), organiser of the event, said on its website. "Please be advised that enhanced security measures are in place, which may result in longer wait times than usual."
