1. “Horrific and significant attack.” A 25-year-old woman has been charged with her mother’s murder in Sydney’s west.

A woman has told a court she couldn’t move her fingers, or wash the blood off properly, after she allegedly decapitated her mother with several knives in their western Sydney home.

Jessica Camilleri on Sunday faced Parramatta Bail Court charged with murder after she allegedly attacked her mother, Rita, in their St Clair home the previous night.

The 25-year-old did not apply for bail, with her lawyer telling the court she had significant health issues.

Magistrate Michael Price made an order for her to be assessed in hospital before her next court appearance.

Camilleri, who appeared via video link, said she couldn’t move her fingers properly after “the incident” and hadn’t been able to wash herself properly in the shower to get all the blood off.

She told the magistrate she had a number of conditions including border autism, bipolar disorder and anxiety.

Detective Superintendent Brett McFadden previously alleged the mother and daughter had been arguing before it turned violent with neighbours raising the alarm.

AAP understands the mother was decapitated but police won’t confirm these reports.

A neighbour was startled to discover police putting a tarpaulin over evidence on his front yard, he told the Daily Mail.

Det Supt McFadden said a number of knives were used in the “horrific” attack on the 57-year-old.

“This is up there with one of the most significant, most horrific scenes police have had to face,” Det Supt McFadden told reporters on Sunday.

“There is no stepping away from the fact that this was horrific and a significant attack, and the injuries that the victim suffered were extensive.”

A four-year-old boy who was in the house was treated at Westmead Children’s Hospital for a minor head injury. He is not Camilleri’s son.

“He is being cared for by his family and getting medical support during the course of the day. The family is distraught as to what has taken place,” Det Supt McFadden said.

Police say they were aware of the family, but what unfolded on Saturday night was “not foreseeable”.

“It is a very difficult, challenging, confronting investigation,” he said.

Strike Force Comeroy has been set up to investigate the incident.

A man is dead and a teenage girl has been taken to hospital with stab wounds after a domestic incident in Sydney.

Police say they were called to a home on Nicholson Street, Chatswood, at about 9.55am on Sunday where the 14-year-old wounded girl was being helped by a member of the public.

She was taken to Sydney Children’s Hospital, reportedly with wounds to her neck, where she remains in a stable condition.

A witness named Melanie told 9News about the incident: “This girl came running out who had been cut in her sleep by her father,” they said. “He started strangling her and she was screaming ‘help me, help me, he’s trying to kill me’.”

Minutes later, emergency services were called to a shopping centre in Sydney’s lower north shore where the 52-year-old man, believed to be the girl’s father, was found severely injured after a fall from an upper level floor. Police say he died at the scene.

Officers have been told there was an altercation between the girl and the man inside a Chatswood home, with the man running from the scene after the girl was assaulted and stabbed.

Anyone needing support is urged to contact 1800 RESPECT (1800 737 732) or Lifeline on 13 11 14.

Oscar winner Natalie Portman will play a female god of thunder in the fourth film from the Chris Hemsworth series, titled Thor: Love and Thunder.

Portman hit the stage at San Diego Comic-Con on Saturday to great fanfare, standing beside returning New Zealand director Taika Waititi and co-stars Hemsworth and Tessa Thompson, where she was handed a Hasbro version the hero’s famous hammer.

“I’ve always had hammer envy,” Portman admitted.

Portman appeared in the first two Thor movies in 2011 and 2013 as Jane Foster, but was absent for the most recent installment, Thor: Ragnarok.

The development shouldn’t come as too much of a surprise for those who read the comic books. Foster’s introduced to the series as an astrophysicist who becomes the object of Thor’s affections, but in a 2014 comic-book storyline, she’s deemed worthy to wield Thor’s hammer, Mjolnir, and adopts the title of Thor, the Goddess of Thunder.

In addition to revealing Portman’s return, the Thor crew also announced a release date for the forthcoming movie: November 5, 2021.

Iran’s envoy to Britain has urged the UK to contain “domestic political forces” which he says want to escalate tension between the two countries amid the capture of a British-flagged tanker in the Gulf by Iran.

“UK government should contain those domestic political forces who want to escalate existing tension between Iran and the UK well beyond the issue of ships.

“This is quite dangerous and unwise at a sensitive time in the region,” Hamid Baeidinejad tweeted.

“Iran however is firm and ready for different scenarios.”
