The rapid spread of footage shows how social media is pivotal in enabling far-right agitators to mobilise internationally

Filmed at about 10.30pm on Monday night on a Belfast street, bystanders captured the moment when a man, believed to be a Sudanese asylum seeker, wielded a knife over another man he had pinned to the ground.

By Tuesday, the clip had become the latest transnational “trigger event” – in the mould of the Southport killings and the case of the murdered 18-year-old student Henry Nowak – as far-right activists from Britain and beyond seized on it.

The writer-director’s second movie lacks some of the craft shown in his later work, but remains a stylish and energetic descent into the cocaine-fulled world of the 70s adult film industry

Masculinity was never more fragile than in Paul Thomas Anderson’s picaresque porn comedyfrom 1997, inspired by the life and times of 70s/80s LA adult movie star John Holmes. It’s a film that delivers the era’s jukebox slams on the soundtrack, though oddly not the Heatwave classic that provides the title. But Boogie Nights gives the male-gaze world of porn a taste of its own phallocentric medicine. How does it feel for a guy to be known and valued for just one thing, and then mocked and even hated when that one thing shrivels?

What happens, in fact, is that our detumescent hero symbolically turns to the more reliably priapic world of guns and crime, although not without first embarrassingly trying to make it as a singer. (David Foster Wallace, in his 1998 essay Big Red Son, about the Adult Movie awards in Las Vegas, compares the event’s musical interludes to the ghastly screeching in Boogie Nights.) Twenty-six-year-old Mark Wahlberg plays handsome young teen Eddie, or Dirk Diggler, as he is later professionally to style himself who, while working behind the bar in a nightclub in California’s San Fernando Valley in 1977 (where he supplements his income by jerking off in the kitchens at the bidding of paying voyeur customers) he meets silver-fox porn impresario Jack Horner, played with leathery assurance and style by Burt Reynolds.

Questioned in France but championed from afar, the departing head coach has forged a legacy that no one – bar, perhaps, himself – would dare dispute

Follow the verdant path towards the Château de Clairefontaine and you are met by a three-metre replica of the World Cup trophy accompanied by two stars, representing France’s World Cup triumphs. Didier Deschamps had his hand in both of them, captaining his side to victory in 1998 before repeating the feat as manager in 2018.

The ‘98 World Cup final was France’s first ever but Les Bleus have now participated in four of the last seven end games, with Deschamps involved in three of them. In North America, he will have one final shot at reaching another. These are the expectations, moulded by past success. Deschamps has taken France to three major finals in his 14-year stint as manager. “We’re among the favourites,” he says as he sits down for the interview. “It isn’t a taboo word for me. If we have this status today, which seems logical and legitimate to me, it’s because of everything that we have done, the results we achieved.”

2-8A Rutland Gate had jewel-encrusted bathroom suites and gold wastepaper bins in its 45 rooms, but has lain empty for years. With many people desperate for secure housing, what does the abandonment of this palace tell us about the UK?

When it last changed hands, in 2020, 2-8A Rutland Gate was Britain’s most expensive house, selling for £210m. The word “house” hardly does it justice; palace is probably more accurate. It is in Knightsbridge, one of the most glamorous parts of London, and has 45 rooms, four lifts, an indoor pool and 116 windows, 68 of which overlook Hyde Park.

But no one is enjoying those views. This palace has been empty for years.

The Ukraine and Iran wars are very different, but a common authoritarian delusion unites the men who started them

A strongman president, self-styled redeemer of national glory, is trapped in a conflict he can’t win but doesn’t know how to end without looking like a loser. A cult of infallibility prevents the leader admitting a strategic blunder even to himself. It could be Donald Trump or Vladimir Putin; Iran or Ukraine.

The conflicts and the regimes involved are also dissimilar in important ways. Russia’s campaign to eradicate a neighbouring democracy is nastier in conception and bloodier in execution than the bungled US effort to dislodge a dictatorship in Tehran. It has also gone on much longer. The first world war was shorter than a “special military operation” that was supposed to capture Kyiv within weeks. The Soviet Red Army repelled Nazi invasion and marched on Berlin in less time than it has taken Putin’s forces to occupy a tranche of eastern Ukraine, and they are not making any significant advances. The war has burned trillions of roubles and sacrificed hundreds of thousands of lives for no discernible dividend in national greatness.

First lady and affected families in audience for highly charged performance of excerpts of Mothers of Kherson

It was hard to imagine an opera with a subject more potentially traumatic – or cathartic – for the assembled audience. The occasion, in the grand and gilded spaces of the National Opera of Ukraine, in Kyiv, was the premiere of excerpts of Mothers of Kherson, an opera about the abduction of Ukrainian children by Russian occupiers – a continuing, raw story of real-life loss and agony.

The opera was originally intended to be about the Maidan protests of 2013-14. But the American librettist George Brant, the author of the hit play Grounded, switched course in 2023 when the stories of abducted children hit the news.

Crowds, including people in masks and hoods, burned vehicles and properties after calls for demonstrations from far-right figures

Protests against immigration have erupted into violence in Northern Ireland after far-right activists called for demonstrations in response to a stabbing attack that was captured in a graphic video.

Crowds including masked men burned vehicles and houses and blocked roads in and around Belfast on Tuesday night, hours after Elon Musk, Tommy Robinson and other agitators exhorted people to take to the streets.

Iran’s Revolutionary Guards Corps says it has targeted an airbase in Jordan hosting US forces, as well as Kuwait and Bahrain, in response to US strikes

• Trump launches strikes against Iran after downing of US army helicopter

If the US genuinely wants a deal it will have to engage with Iranian demands on sanctions relief, says Danny Citrinowicz, the former head of the Iran branch of Israeli military intelligence.

Today’s exchange of strikes shows how easily both Iran and the US can slide towards another round of escalation, says Citrinowicz, who is now a nonresident fellow at the Atlantic Council.

If Washington is unwilling to accept that reality, it should recognize the likely alternative: continued confrontations with Iran that could eventually spiral beyond anyone’s control and lead to military conflict under less favorable conditions.

Even a limited military campaign designed to weaken Iran would not fundamentally alter Tehran’s negotiating position. It has not happened in the past, and there is little reason to believe it would happen now. Iran emerges from the latest exchange of blows convinced that it can absorb pressure and respond to attacks.”

Legal and moral responsibility of all countries in the region (especially those located along the southern shores of the Persian Gulf) to prevent the US military and Israel from using their territory or facilities to plan, organise, execute, or support hostile actions against Iran”.

Conservationists say cherished creatures such as whales, dolphins and seabirds are being killed in large numbers by fishing tackle

Thousands of Britain’s most charismatic and protected marine wildlife, including whales, porpoises, dolphins, seals and seabirds are being killed as “collateral damage” by fishing vessels every year, according to the first-ever analysis of bycatch data.

The analysis, by the Wildlife and Countryside Link, a coalition of voluntary conservation groups, reveals the devastating toll bycatch, the accidental capture and killing of non-target species by fishing vessels, is having on marine species.

Chair of prisons and detention watchdog concerned about intimidating effect as wide-ranging and damning review published

• Grim reality of prison conditions laid bare in damning report

Staff at an immigration detention centre wore England flags pinned to their uniforms while guarding migrants, a report from the prisons and detention watchdog has revealed.

Their use by staff at one of the Home Office’s short-term holding facilities to detain migrants is revealed in the Independent Monitoring Boards’ national annual report, published on Wednesday, which is based on 127 annual reports about different prisons, young offender institutions and immigration detention centres.
