Mourners have gathers to pay tribute to Republican Activist Charlie Kirk after he was fatally shot at Utah University.

Various flags and lit candles have been placed at a makeshift vigil outside Timpanogos Regional Hospital.

One sign read: “RIP Charlie Kirk — you are not silent.”

Mr Kirk was shot in the neck on Wednesday during an event at Utah Valley University in Orem.

The co-founder and president of the conservative student group Turning Point USA was pronounced dead at a local hospital hours later.
