Social media users have been urged not to share a video taken by a gunman involved in attacks on two mosques in New Zealand that left 50 people dead.
The country's national police force called on people not to spread the "extremely distressing footage" after worshippers were killed during Friday prayers.
The message has been echoed by New Zealand's Prime Minister Jacinda Ardern.
Sky News has decided not to show the video. Instead, we are showing six stills from the footage, where the gunman identifies himself.
In his social media posts he calls himself Brenton Tarrant.
As he starts his car, he mutters to himself: "Let's get this party started."
Three shotguns can be seen on the front passenger seat.
Tarrant's legs are visible underneath the steering wheel, his trousers with padded knees - the kind worn by police or military assault teams.
He is also wearing ammunition magazines around his waist.
The gunman turns the camera on himself - a young white man. Closely cropped hair. Reportedly in his late 20s.
"Hello lads," he begins, calmly.
Aware he is probably being watched, by followers around the world on his live-stream.
He parks his car on a side road next to the mosque, off the main street and gets out, wearing camouflage gloves on his hands and holding a gun.
A military marching song is playing in the background of the video - identified it as The British Grenadiers March.
In the car boot, next to some plastic shopping bags, are some red fuel cans and at least two more guns.
They are graffitied with writing in white ink, showing dates of historic Christian battles and names of well-known far-right extremists.
As he walks from the car, around the corner, fully armed, he ignores three people on the street.
He is focused on his objective: the mosque and the Muslims worshipping inside.
As the first victim walks out of the mosque, Brenton Tarrant raises his rifle.
Speaking about the footage, New Zealand police said they were "aware there is extremely distressing footage relating to the incident in Christchurch circulating online".
"We would strongly urge that the link not be shared," the force said in a statement.
"We are working to have any footage removed."
A man aged in his 20s has been charged with murder following the shootings at the al Noor mosque in the city of Christchurch and then the nearby Linwood mosque.
Three other people - two men and a woman - were also arrested after the attacks.
