Thousands of members of the police force and public gathered to honour Constables Matthew Arnold and Rachel McCrow after they were killed in the line of duty.

Elon Musk has officially vowed to step down as Twitter's CEO after 10 million people on the social media platform voted for his resignation.

More than half of 17.5 million users who responded to the poll that asked whether the billionaire should quit voted yes on Sunday.

The results prompted Musk to confirm today that he will stand down when he finds "someone foolish enough" to take on the position.

He will still remain as owner.

Posting to Twitter, Musk clarified how his role will change.

"I will resign as CEO as soon as I find someone foolish enough to take the job," Musk said.

"After that, I will just run the software and servers teams."

The multi-billionaire and Tesla founder has clashed with users on multiple fronts since he bought the company for $US44 billion back in October and has made a number of controversial moves in recent weeks that have ruffled feathers.

In a recent significant policy change, Twitter had announced that users will no longer be able to link to Facebook, Instagram, Mastodon and other platforms the company described as "prohibited."

But that decision generated so much immediate criticism, including from past defenders of Twitter's new billionaire owner, that Musk promised not to make any more major policy changes without an online survey of users.

The action to block competitors was Musk's latest attempt to crack down on certain speech after he shut down a Twitter account last week that was tracking the flights of his private jet.

The nation has farewelled two police officers killed in last week's deadly ambush near Chinchilla in southern Queensland.

Thousands of others around Queensland gathered while the memorial unfolded around the state to pay tribute to the young officers murdered at the Wieambilla property.

'You are a hero': Constable Matthew Arnold remembered

Arnold's close family friend Senior Sargeant Laura Harriss said the police force was a second family to the constable.

She read a letter written by Arnold in Year 12 which said: "I may be gone some day, soon perhaps, but just know that I will never leave you. I will cherish every moment we've had together in my heart forever".

Arnold was said to be proud to be a police officer and had found his true passion and purpose with his family, friends and colleagues honouring his service.

"You are a hero and will never be forgotten," Harris said.

"May your name and memory never leave the mind of others."

Constable Rachel McCrow described as 'one of a kind'

McCrow's colleague and friend Senior Constable Melissa Gibson said she was the "very essence of compassion and selflessness".

"Rach was simply one of a kind," Gibson said.

"Behind all of that was this cheeky larrikin, who loved a good prank and loved a good meme, often at our expense.

"I'm so proud of you for the courage you displayed in your final moments, and for being the fighter that you are. "

Gibson apologised for not being there for McCrow in her time of need during the ambush.

"That is something that will forever haunt me," she said.

Dignitaries pay tribute to officers who dedicated their lives to the force of good

Police chaplain Jeffrey Baills directed a message to Arnold and McCrow's families that they should be "so proud" of the pair for their service during their final moments.

"What happened on December 12 was un-Australian and does not belong in this country," he said.

"This barbaric act has shocked our community and it's irreparably damaged your (families).

"Today our hearts bleed blue."

Premier Annastacia Palaszczuk said in a world filled with anger, division and ugliness, McCrow and Arnold were a force for good.

"They dedicated their lives to it," she said.

"There are no words that can heal this awful grief and crushing loss.

"We will rededicate ourselves to their example of there being far more good than there is evil. In honour of two young people who lived what they believed, Rachel and Matthew."

Queensland Police Commissioner Katrina Carroll awarded Arnold and McCrow the national police service medal and national medal which are normally given to officers after 15 years of "diligent and ethical service".

"Both the Queensland Police Service and the community have lost two exceptional police officers," she said.

McCrow and Arnold were killed when what was believed to be a routine missing persons check at the property last Monday, turned into a deadly ambush.

They were both gunned down by brothers Nathaniel and Gareth Train, along with Gareth's wife Stacey.

Their fellow officers Keeley Brough and Randall Kirk survived, which Carroll later said was a "miracle".

The Trains were killed later in the night during a shootout with specialist police.

Both Brough and Kirk attended the service today.

The public memorial was followed by private funeral services for both officers.

A boisterous kangaroo has been captured on CCTV invading a Melbourne backyard, descending on the property from metres above – much to the surprise of an unsuspecting pet.

The little dog, named Ollie, was given the fright of its life after the roo – spotted on camera at the home in South Morang yesterday – bounced over the fencing and crash landed on the pavement.

Ollie can be seen initially running away in fear before curiosity gets the better of it and is then seen returning back to investigate.

Watch the video above.

The two animals then briefly circle the perimeter of the yard before the dog escapes down a set of stairs to safety.

Despite the brief excitement, neither roo nor pooch was injured during the ordeal.

The owners of the Melbourne property confirmed that Ollie is safe and well and the kangaroo was released safely back into the wild. 

One family in Queensland has had a very unwelcome surprise when their feline left an "unexpected present" under the family Christmas tree.

The family's pet cat caught and dropped a venomous red-bellied black snake under their Christmas tree earlier this week.

Photos uploaded by Gunter Glaser, from Darling Downs Snake Catchers, show the reptile curled inauspiciously amongst a pile of presents.

Glasser told 9news.com.au the snake was relatively small, measuring around 60 centimetres.

Both the snake and the cat were unharmed in the incident.

"The cat wasn't bitten and quite proud of itself ," he said.

"Thankfully, the snake had no negative effect from the cat carrying it."

Gunter said he relocated the snake to bushland by a creek.

"The family are snake lovers, but didn't want to touch it," he said,

"It was an unexpected Christmas present."

There have no recorded deaths from red-bellied black snakes in Australia, but the snakes are considered venomous and dangerous to humans.

According to the Australian Museum symptoms of envenomation include: bleeding and/or swelling at the bite site, nausea, vomiting, headache, abdominal pain, diarrhoea, sweating, local or general muscle pain, weakness, and red-brown urine.

Glasser previously told 9news.com.au sometimes people don't even realise they have been bitten, as there's often no pain from a bite.

The experienced snake catcher was bitten by a venomous eastern brown snake last month and rushed to hospital. 

The encounters come in the midst of snake season, which typically run from September – April. 

A remote Black Sea island less than a kilometre wide has become a symbol of defiance. But the myths surrounding it go back further than that.

An explosion during repairs on a section of a Europe-bound natural gas pipeline in western Russia has killed three people but didn't affect export supplies, officials said.

The explosion on Tuesday ripped through a section of the Urengoy-Pomary-Uzhhorod pipeline in the Chuvashia region during repair work. Three repair workers were killed and one was injured by the blast, which sent a huge plume of burning gas skyward, regional authorities said.

The pipeline that originates at a gas field in Siberia and crosses Ukraine along its way to Europe is one of the main routes for Russian gas exports to the EU.

Chuvashia's governor, Oleg Nikolayev, said in televised remarks that it wasn't immediately clear how long it would take to fix the section of the pipeline cut by the explosion.

The regional branch of Russia's state-controlled natural gas giant, Gazprom, said volumes of gas transportation weren't affected by the blast as supplies were rerouted along parallel lines.

The pipeline crossing Ukraine has become the main conduit for Russian natural gas supplies to Europe since an explosion ripped through the Nord Stream 1 and 2 pipeline under the Baltic Sea in September, causing extensive damage.

Investigators in Sweden have found traces of explosives at the Baltic Sea site where two natural gas pipelines were damaged in an act of "gross sabotage," but they stopped short of apportioning blame.

Russian President Vladimir Putin has accused the West of blowing up the pipelines and singled out the United States as profiting from attacks on Europe's energy infrastructure, while some Nordic and other European news outlets have alleged Moscow's involvement.

Nord Stream 1 carried Russian gas to Germany until Moscow cut off supplies at the end of August, citing equipment problems. German officials dismissed that explanation as cover for a political decision to push up prices and create uncertainty.

Nord Stream 2 never entered service as Germany suspended its certification process shortly before Russia sent its forces into Ukraine in February.

A 97-year-old former secretary at a Nazi concentration camp has been convicted for her role in the murder of 10,505 people during the Holocaust, in what could be the final trial of its kind.

Irmgard Furchner worked as a stenographer and typist at the Stutthof camp near Gdansk in Nazi-occupied Poland, from 1943 until the end of the Nazi regime in 1945.

She was sentenced on Tuesday to a two-year suspended sentence, according to a spokesperson at the court in Itzehoe, northern Germany.

As Furchner was an adolescent at the time of the crimes, the 97-year-old's trial took place before a juvenile court and her sentence will see her placed into juvenile probation, the court confirmed to CNN.

In her closing statement, Furchner said she was sorry for what had happened and regretted that she had been at Stutthof at the time.

Furchner went on the run weeks before her trial was due to begin, but was found by authorities after several hours. Proceedings eventually began late last year.

Efraim Zuroff, the top Nazi hunter at the Simon Wiesenthal Center, said that "today's verdict is the best that could be achieved, given the fact that she was tried in a juvenile court".

"In view of Furchner's recent statement to the court that she 'regretted everything', we were concerned that the court might accept her defence attorney's plea for an acquittal," Zuroff said in a statement.

"Yet given her claim that she had no knowledge of the murders being committed in the camp, her regret was far from convincing."

Prosecutors in Itzehoe said during the proceedings that Furchner's trial may be the last of its kind.

However, a special federal prosecutors' office in Ludwigsburg tasked with investigating Nazi-era war crimes says another five cases are currently pending with prosecutors in various parts of Germany, where charges of murder and accessory to murder aren't subject to a statute of limitations.

Germany has raced to bring the perpetrators of Nazi war crimes to justice in recent years, before it is too late. But experts say that only a small proportion of those involved ever faced a court.

Tens of thousands of people were held in brutal conditions at the Stutthof camp, and more than 60,000 died there.

Stutthof mainly held non-Jewish Poles, as well as a large number of Jews from the Polish cities of Warsaw and Bialystok and from Nazi-occupied Baltic states, according to the museum.

Human remains have been found after a fire at a rural property in Queensland's North Burnett region.
