An expert has told Sky News the attack on a Moscow concert hall is consistent with Islamic State.
Sky News has analysed IS footage of the attack and an image released by the militant group and spoken to experts about what the materials reveal.
Aaron Zelin, an expert on jihadist groups and senior fellow at the Washington Institute for Near East Policy, said “the attack itself, the type of people involved, the style of the attack and the media campaign” is all “Islamic State modus operandi”.
IS has said it carried out the shooting massacre, and US officials have said their intelligence indicates that an Afghan affiliate, Islamic State Khorasan, or IS-K, was responsible. However, Vladimir Putin has not publicly mentioned IS in connection with the assailants.
The video
A day after the attack, IS released a video of the assailants inside Crocus Hall via the militant group’s Amaq news agency which shows a number of gunmen storming the building and attacking people.

The attackers are seen holding guns and also knives. More than 130 people were killed and over 180 others were injured on Friday night.
Mr Zelin said the type of weapons used in the attack are consistent with IS methods. “We’ve seen in past attacks they shoot people and stab people… They have as many weapons on them as possible so they can inflict as much damage on them as possible.
“So, if they end up using all their bullets and cartridges or AK-47s they will still have a knife to stab.”

While IS has also used other methods in previous attacks, including suicide attacks, another expert said that it would likely be easier to “procure firearms in Russia”.

Dr Antonio Giustozzi, a senior research fellow at the Royal United Services Institute, said the way IS carries out attacks “depends on the kind of weapons they can obtain”.
“So explosives, especially plastic explosives that you can use for suicide belts is not so easy to procure…. It’s probably easier to procure firearms in Russia.” He added the “exact choice of weapons can be dictated by what’s available on the black market”.
Clothing worn by suspects match IS image
IS also released an earlier image which they say shows some of the people behind the Moscow attack. It shows four people with blurred faces in front of an IS flag.

Mr Zelin said images “pledging allegiance to the leader of IS” are part of the group’s media campaign.
Sky News has analysed and compared the IS image to subsequent interrogation videos and images by Russian authorities and other photos later taken of the four suspects in court. We used a facial recognition tool and analysed the clothing worn by the suspects.
Clothing worn by three of the people seen in the IS image matches those seen in other videos and images appearing in the aftermath of the attack.

We brightened the IS image above and matched details on the T-shirts worn by three of the people – to other images and videos on Telegram showing them being interrogated by Russian authorities.

The suspects have been named as Dalerdzhon Mirzoyev, Saidakrami Murodali Rachabalizoda, Muhammadsobir Fayzov and Shamsidin Fariduni.
We cross referenced the aftermath imagery and videos to photos of the four suspects pictured in court using an AI facial recognition tool which confirmed they matched.
Mr Zelin said that while not all IS attacks are the same, there is a consistency to the group’s media campaign.
He explained they often include a line to first claim responsibility, followed by a longer statement, then “photographic evidence of the individuals pledging allegiance to the leader of IS”, followed by some form of video of the attack or to do with the attack.
“It’s definitely a template they use, part of it is to keep them in the news for a longer time,” he added.

Claiming responsibility for attack
Experts are convinced no other group is responsible.
Dr Giustozzi said: “This is about, intimidating, spreading terror and primarily the recruitment and funding for the militant group.”
Mr Zelin said in the aftermath of attack, he had seen in their “different types of propaganda in a number of different languages that they are trying to recruit people”.
Russia’s president Vladimir Putin has not publicly mentioned Islamic State in connection with the assailants, who he said had been trying to flee to Ukraine with help from “the Ukrainian side”.
Ukraine has denied any role and Volodymyr Zelenskyy has accused Putin of seeking to divert blame.
Washington said it had warned Russia this month of an imminent attack. A source familiar with this intelligence said it was based on interceptions of “chatter” among IS-K militants.
An Israeli reservist who served three tours of duty in Gaza has told Sky News in a rare on-camera interview that his unit was often ordered to shoot anyone entering areas soldiers defined as no-go zones, regardless of whether they posed a threat, a practice he says left civilians dead where they fell.
“We have a territory that we are in, and the commands are: everyone that comes inside needs to die,” he said. “If they’re inside, they’re dangerous you need to kill them. No matter who it is,” he said.
Speaking anonymously, the soldier said troops killed civilians arbitrarily. He described the rules of engagement as unclear, with orders to open fire shifting constantly depending on the commander.
The soldier is a reservist in the Israel Defence Force’s 252nd Division. He was posted twice to the Netzarim corridor; a narrow strip of land cut through central Gaza early in the war, running from the sea to the Israeli border. It was designed to split the territory and allow Israeli forces to have greater control from inside the Strip.
He said that when his unit was stationed on the edge of a civilian area, soldiers slept in a house belonging to displaced Palestinians and marked an invisible boundary around it that defined a no-go zone for Gazans.
“In one of the houses that we had been in, we had the big territory. This was the closest to the citizens’ neighbourhood, with people inside. And there’s an imaginary line that they tell us all the Gazan people know it, and that they know they are not allowed to pass it,” he said. “But how can they know?”
People who crossed into this area were most often shot, he said.

“It was like pretty much everyone that comes into the territory, and it might be like a teenager riding his bicycle,” he said.

The soldier described a prevailing belief among troops that all Gazans were terrorists, even when they were clearly unarmed civilians. This perception, he said, was not challenged and was often endorsed by commanders.
“They don’t really talk to you about civilians that may come to your place. Like I was in the Netzarim road, and they say if someone comes here, it means that he knows he shouldn’t be there, and if he still comes, it means he’s a terrorist,” he said.
“This is what they tell you. But I don’t really think it’s true. It’s just poor people, civilians that don’t really have too many choices.”
He said the rules of engagement shifted constantly, leaving civilians at the mercy of commanders’ discretion.
“They might be shot, they might be captured,” he said. “It really depends on the day, the mood of the commander.”
He recalled an occasion of a man crossing the boundary and being shot. When another man came later to the body, he too was shot.
Later the soldiers decided to capture people who approached the body. Hours after that, the order changed again, shoot everyone on sight who crosses the “imaginary line”.

At another time, his unit was positioned near the Shujaiya area of Gaza City. He described Palestinians scavenging scrap metal and solar panels from a building inside the so-called no-go zone.
“For sure, no terrorists there,” he said. “Every commander can choose for himself what he does. So it’s kind of like the Wild West. So, some commanders can really decide to do war crimes and bad things and don’t face the consequences of that.”
The soldier said many of his comrades believed there were no innocents in Gaza, citing the Hamas-led 7 October attack that killed around 1,200 people and saw 250 taken hostage. Dozens of hostages have since been freed or rescued by Israeli forces, while about 50 remain in captivity, including roughly 30 Israel believes are dead.
He recalled soldiers openly discussing the killings.
“They’d say: ‘Yeah, but these people didn’t do anything to prevent October 7, and they probably had fun when this was happening to us. So they deserve to die’.”
He added: “People don’t feel mercy for them.”
“I think a lot of them really felt like they were doing something good,” he said. “I think the core of it, that in their mind, these people aren’t innocent.”

In Israel, it is rare for soldiers to publicly criticise the IDF, which is seen as a unifying institution and a rite of passage for Jewish Israelis. Military service shapes identity and social standing, and those who speak out risk being ostracised.
The soldier said he did not want to be identified because he feared being branded a traitor or shunned by his community.
Still, he felt compelled to speak out.
“I kind of feel like I took part in something bad, and I need to counter it with something good that I do, by speaking out, because I am very troubled about what I took and still am taking part of, as a soldier and citizen in this country,” he said
“I think the war is… a very bad thing that is happening to us, and to the Palestinians, and I think it needs to be over,” he said.
He added: “I think in Israeli community, it’s very hard to criticise itself and its army. A lot of people don’t understand what they are agreeing to. They think the war needs to happen, and we need to bring the hostages back, but they don’t understand the consequences.
“I think a lot of people, if they knew exactly what’s happening, it wouldn’t go down very well for them, and they wouldn’t agree with it. I hope that by speaking of it, it can change how things are being done.”

We put the allegations of arbitrary killings in the Netzarim corridor to the Israeli military.
In a statement, the IDF said it “operates in strict accordance with its rules of engagement and international law, taking feasible precautions to mitigate civilian harm”.
“The IDF operates against military targets and objectives, and does not target civilians or civilian objects,” the statement continued.
The Israeli military added that “reports and complaints regarding the violation of international law by the IDF are transferred to the relevant authorities responsible for examining exceptional incidents that occurred during the war”.
On the specific allegations raised by the soldier interviewed, the IDF said it could not address them directly because “the necessary details were not provided to address the case mentioned in the query. Should additional information be received, it will be thoroughly examined.”
The statement also mentioned the steps the military says it takes to minimise civilian casualties, including issuing evacuation warnings and advising people to temporarily leave areas of intense fighting.
“The areas designated for evacuation in the Gaza Strip are updated as needed. The IDF continuously informs the civilian population of any changes,” it said.
An Australian mother has been found guilty of murdering her estranged husband’s parents and an aunt by serving them a beef wellington laced with poisonous mushrooms.
Erin Patterson, 50, invited her former parents-in-law, Don and Gail Patterson, both 70, and Gail Patterson’s sister, Heather Wilkinson, 66, to the fatal lunch on 29 July 2023.
The mother-of-two, from the state of Victoria in southern Australia, has also been convicted of the attempted murder of Mrs Wilkinson’s husband Reverend Ian Wilkinson.
All four fell ill after eating a meal of beef wellington, mashed potatoes and green beans at Patterson’s home in the town of Leongatha, the court was told.
Prosecutors said Patterson knowingly laced the beef pastry dish with deadly death cap mushrooms, also known as Amanita phalloides, at her home.
The guests ate their meals off four large grey dinner plates, while Patterson ate from a smaller, tan-coloured plate, the court heard.
Mrs Wilkinson and Mrs Patterson died on Friday 4 August 2023, while Mr Patterson died a day later.

Her estranged husband Simon Patterson, with whom she has two children, was also invited to the lunch and initially accepted but later declined, the trial heard.
The jury was told that prosecutors had dropped three charges that Patterson had attempted to murder her husband, who she has been separated from since 2015.
Reverend Wilkinson said that immediately after the meal, Patterson fabricated a cancer diagnosis, suggesting the lunch was put together so that she could ask them the best way to tell her children about the illness.
The trial attracted intense interest in Australia – with podcasters, journalists and documentary-makers descending on the town of Morwell, around two hours east of Melbourne, where the court hearings took place.
A sentencing date is yet to be scheduled.
What makes death cap mushrooms so lethal?
The death cap is one of the most toxic mushrooms on the planet and is involved in the majority of fatal mushroom poisonings worldwide.
The species contains three main groups of toxins: amatoxins, phallotoxins, and virotoxins.
From these, amatoxins are primarily responsible for the toxic effects in humans.
The alpha-amanitin amatoxin has been found to cause protein deficit and ultimately cell death, although other mechanisms are thought to be involved.
The liver is the main organ that fails due to the poison, but other organs are also affected, most notably the kidneys.
The effects usually begin after a short latent period and can include gastrointestinal disorders followed by jaundice, seizures, coma, and eventually, death.

Israel says its military has attacked Houthi targets at three ports and a power plant in Yemen.
Defence minister Israel Katz confirmed the strikes, saying they were carried out due to repeated attacks by the Iranian-backed rebel group on Israel.
Mr Katz said the Israeli military attacked the Galaxy Leader ship which he claimed was hijacked by the Houthis and was being used for “terrorist activities in the Red Sea”.

It came after the Israel Defense Forces (IDF) issued an evacuation warning for people at Hodeidah, Ras Issa, and Salif ports – as well as the Ras al Khatib power station, which it said is controlled by Houthi rebels.
The IDF said it would carry out airstrikes on those areas due to “military activities being carried out there”.
Afterwards, Mr Katz confirmed the strikes at the ports and power plant.
Earlier in the day, a ship was reportedly set on fire after being attacked in the Red Sea.
A private security company said the assault, off the southwest coast of Yemen, resembled that of the Houthi militant group.

From May: Israel strikes Yemen’s main airport
It was the first such incident reported in the vital shipping corridor since mid-April.
The vessel, identified as the Liberian-flagged, Greek-owned bulk carrier Magic Seas, had taken on water after being hit by sea drones, maritime security sources said. The crew later abandoned the ship.
The Houthi rebels have been launching missile and drone attacks against commercial and military ships in the region in what the group’s leadership called an effort to end Israel’s offensive against Hamas in Gaza.
Between November 2023 and January 2025, the Houthis targeted more than 100 merchant vessels with missiles and drones, sinking two of them and killing four sailors.
The Houthis paused attacks in a self-imposed ceasefire until the US launched an assault against the rebels in mid-March.
That ended weeks later and the Houthis have not attacked a vessel, though they have continued occasional missile attacks targeting Israel.
A renewed Houthi campaign against shipping could again draw in US and Western forces to the area.
The ship attack comes at a sensitive moment in the Middle East.
A possible ceasefire in the Israel-Hamas war hangs in the balance and Iran is weighing up whether to restart negotiations over its nuclear programme.
It follows American airstrikes last month, which targeted its most-sensitive atomic sites amid an Israeli war against the Islamic Republic that ended after 12 days.
How did the Houthis come to control much of Yemen?
A civil war erupted in Yemen in late 2014 when the Houthis seized Sanaa.
Worried by the growing influence of Shia Iran along its border, Saudi Arabia led a Western-backed coalition in March 2015, which intervened in support of the Saudi-backed government.
The Houthis established control over much of the north and other large population centres, while the internationally recognised government based itself in the port city of Aden.
