- US right-wing activist Charlie Kirk was shot and killed during an event in Utah on Thursday.

Prime Minister Anthony Albanese says the fatal shooting of right-wing commentator Charlie Kirk is "horrific" as he condemned political violence.
Kirk, a 31-year-old podcast-radio commentator and ally of United States President Donald Trump, is credited with helping build the Republican Party's support among younger voters.
He was killed on Thursday AEST by a single gunshot at an event in the US state of Utah, which governor Spencer Cox called a political assassination.
"This is horrific. There is no place for violence," Albanese told reporters on Friday.
"I think the world is shocked by such an event and my heart goes out to Mr Kirk’s family and to all those who will be grieving today in the United States."
His words echoed Deputy Prime Minister Richard Marles a day earlier, who told Sky News the government's thoughts were with the family of Kirk.
"Our thoughts go out to the family of Charlie Kirk. This is an absolute tragedy," he said.
"We condemn any form of political violence. It really matters that political discourse occurs peacefully and through dialogue and conversation."

"It’s absolutely shocking news, and some terrible images are coming out of the United States," he told ABC Radio.
"Charlie Kirk is obviously a prominent conservative political activist and someone who's very close to President Trump.
"So I think it’s highly likely that you’re right, that this is an act of political violence. And that is a very distressing thing for those of us who think fondly of the United States."
It comes as investigators in the United States say they have found a bolt-action rifle they believe was used to kill Kirk and released images of a "person of interest" as they searched for the shooter they described as "college age".
Federal Bureau of Investigation (FBI) and state officials said the killer arrived on the campus a few minutes before the event began, a talk by Kirk titled Prove Me Wrong outdoors in front of about 3,000 people at Utah Valley University in Orem, Utah, about 65km south of Salt Lake City.
Security-camera videos show an armed individual ascending stairwells to get onto a roof before firing at Kirk, the officials told a news conference.
Kirk, a staunch defender of gun rights, was answering an audience question about mass shootings when the bullet struck his neck, prompting audience members to flee in panic.
The shooter jumped off the roof and fled into an adjoining neighbourhood, Robert Bohls, the FBI special agent in charge, told reporters.
Rifle found nearby as search continues
Investigators found a "high-powered bolt-action" rifle in a nearby wooded area, and were examining that along with palm prints and footprints for clues.
Early Friday AEST, with classes cancelled, the roof of the building on the otherwise deserted campus and the nearby woods were strung with yellow tape as investigators scoured them for evidence.

The shooter has not been publicly identified, but the FBI circulated grainy images apparently taken from security cameras showing a "person of interest": a person wearing a black top, black sunglasses and a dark baseball cap.
"The FBI is offering a reward of up to [US]$100,000 ($150,000) for information leading to the identification and arrest of the individual(s) responsible for the murder of Charlie Kirk," the bureau said.
