Tate Modern, London
The Sámi artist may use reindeer skulls and bones, but her spiralling wooden fences are so slight they fail to impose themselves on the venue’s vast space – or the imagination

The Tate Turbine Hall, in case you didn’t know, is quite big. It gives an artist a unique opportunity to work on an epic scale and animate this colossal post-industrial space all the way from piazza floor to girdered roof. Artists have put the sun in here, built slides, opened a crack from one end of the floor to another. Yet Máret Ánne Sara seems either scared, repelled or just uninspired by it. She has built a little fort of sticks to hide away from the vastness. That’s the best I can say about her installation – that a small child might enjoy it as a pretend stockade. This easy-to-escape maze of trees actually reminds me of an upmarket adventure playground.

It’s hard to understand why Tate Modern didn’t ask Sara for a bit more, well, art. She must have submitted drawings. Did these not suggest it was all going to be rather slight? You do know, they might have gently said, this is the space Ai Weiwei carpeted with sunflower seeds, and Rachel Whiteread filled with a simulacrum of Arctic ice?

From Annie Hall to The First Wives Club, Keaton’s performances redefined what it meant to be funny, stylish and unapologetically oneself. Our writers pay tribute to a one-off star who made eccentricity irresistible

When 50 men went on trial in France, accused of raping a woman who had been drugged by her husband, Manon Garcia was in the courtroom – and in the prosecutors’ closing arguments. How does she make sense of what happened?

‘It is so rare, in fact it never happens, that crimes are so well documented.” Manon Garcia is the French feminist philosopher whose thinking featured so prominently in the final stages of the Dominique Pelicot trial. There are, she points out, 20,000 videos and photos of Gisèle Pelicot “being raped, unconscious, by complete strangers”. One might struggle to understand why, in the face of such compelling factual evidence against her husband Dominique and a further 50 men, prosecutors would need to bring in a philosophical argument to explain why this was wrong. But since they did, they couldn’t have found a clearer or more persuasive voice than Garcia’s, the author of We Are Not Born Submissive and The Joy of Consent.

Last November, six weeks into the trial, Garcia arrived in Avignon to watch mass rape in the dock. She had intended to come for a day or two, just to see it, and then go back to her normal life. “But I was seeing things that the journalists were not seeing, because we’re not doing the same job. Also, something deeper happened. It felt like I couldn’t do anything else. My kids were three and five, and I could not be a mother, be in my daily life, while the trial was happening.”

It was a brutal killing spree that gripped Italy – yet so little is still known. Why were lovers murdered in their cars? Why were their sexual organs often targeted? Author Tobias Jones sifts the evidence

Some criminal cases are so vast that even the number of victims is uncertain: in the case of the unsolved “Monster of Florence” crimes that have gripped Italy for half a century, it is known that seven couples were murdered. But some say it’s eight, and at least another 16 murders have been connected to the case. The number of suspects almost matches that of the victims. First there was the pista sarda, the Sardinian line of enquiry into the swinging, pimping Vinci brothers who probably had a hand in the “first” murder in 1968. In the 1990s, a rapist, Pietro Pacciani, was convicted and then cleared. In 2000, Pacciani’s co-accused, Mario Vanni and Giancarlo Lotti, were sentenced to life and 28 years respectively for the murders committed between 1981 and 1985.

Gianluca Monastra, author of Il Mostro di Firenze, writes that it’s a case in which “there’s a seductive and ever more abstract ballet of hypotheses … it’s a story in which everything can seem true, as can its contrary.” Filled with intrigue and sex (most of the victims were young couples making out in the countryside), it has spawned its fair share of obsessives, who have come to be known as monsterologists. The frequency with which evidence suddenly appeared or disappeared has persuaded some monsterologists to suspect that elements within law enforcement were involved.

Fiona Benson was invited to Lviv’s BookForum by Ukrainian poet-soldier Artur Dron’. She recounts falling in love with the city and its thriving literary culture, before an air raid siren sounds

I had been working on Exeter University’s Ukrainian Wartime Poetry project for two years when the invitation came to travel to the country’s largest literary festival. I didn’t exactly relish the prospect of a journey to a war zone, but I was assured that visiting BookForum in Lviv, a city so far west it’s practically in Poland, would be safe. I had been leading poetry workshops with exiles and editing translations of Ukrainian poetry, including soldier Artur Dron‘’s collection We Were Here, published last November. So, when Artur and his translator – the incredible poet Yuliya Musakovska – asked me and language professor Hugh Roberts to attend, I couldn’t say no.

What I didn’t expect was to fall in love with the city: its gorgeous architecture, its cafes, its parks full of trees, and its writers. Lviv’s inspired, robust literary culture puts the UK’s own underfunded, last-gasp scene to shame. On the first night of the Forum, Hugh and I attended a nonstop music and poetry event in a nightclub at which both Artur and Yuliya read their poems, and revealed what utter rock stars they truly are. I don’t know why I was surprised; We Were Here, written on the frontline before Artur was even 22, is a masterpiece. It is full of lucid, clear-eyed accounts of his experiences in the trenches and on the battlefield, elegies for his comrades, humane portraits of the suffering of bereaved civilians and furious adaptations of liturgies and prayers. One of his poems is published below.

Explore the Guardian’s tracker to see which operators are nationalised and if services are improving under public ownership

The majority of Great Britain’s major rail operators are now in public ownership, as the Labour government continues its efforts to make the railways “more reliable, affordable and accessible”.

The nationalisation of Greater Anglia on 12 October represents the ninth major passenger service to be brought back into public ownership, leaving seven to go before the government’s deadline of completing every operator by 2027.

US president in Egypt alongside world leaders after Israeli families welcome hostages home and Palestinian detainees are freed

• Hamas releases 20 remaining living Israeli hostages

• Joy and sorrow as Palestinian prisoners and detainees return

Donald Trump has questioned whether former UK prime minister Tony Blair will serve on a new “board of peace” that is intended to oversee the governance of Gaza.

The US president’s comments come amid ongoing criticisms of Blair for his role in the Iraq war that began in 2003.

In speech to Israeli Knesset hours after hostages released, US president spoke of ‘historic dawn of new Middle East’

• Gaza ceasefire – live updates

Donald Trump has vowed to use the power of his presidency to ensure that Israel recognises it has achieved “all that it can by force of arms”, and begin an age of cooperation in the Middle East that may ultimately extend as far as peace with Iran.

In a speech to the Israeli Knesset, made hours after the last remaining Israeli hostages were released from Gaza, Trump hailed the “historic dawn of a new Middle East” and an end to the “long and painful nightmare” of the Gaza war.

On a powerfully emotional day, 20 Israelis went home, hundreds of Palestinians were freed from prison and Trump had his perfectly scripted moment

The estimated 65,000 people in “hostages square” in Tel Aviv heard it before they saw it. Like so many sunflowers, their faces turned up to search the clear blue morning sky for the source of the sound. Then it swept into view from the west, from the direction of Gaza.

A helicopter, military brown, was on the way to Ichilov hospital a few hundred metres away. But it diverted. It circled around the crowd giving each person below a view, and then tilted to its right, in an apparent salute to the cheering, waving, smiling faces below.

Nearly 2,000 people, including about 1,700 seized from Gaza and held without charge, set free from Israeli jails

The police could not hold the crowds back. As soon as they saw the Palestinian prisoners and detainees through the windows of the bus, hundreds of people gathering in front of a theatre in Ramallah in the occupied West Bank rushed forward, chanting the names of loved ones they had not seen for years or, in some cases, decades.

Their faces were gaunt, the sharp angles decorated by freshly scabbed-over wounds. Loved ones hoisted them up on their shoulders with ease. One, swaddled in a Palestinian keffiyeh and splaying his fingers into a V for victory, was dropped before his mother, whose feet he began to kiss.
