Ecce Homo will be museum’s second Caravaggio, after being spotted on sale in Spanish capital in 2021

A lost Caravaggio painting of the scourged and thorn-crowned Christ that was misattributed and almost sold for just €1,500 is to go on show at the Prado museum in Madrid three years after its discovery shocked the art world and made headlines across the globe.

The Ecce Homo, which measures 111cm by 86cm, had been attributed to the circle of the 17th-century Spanish artist José de Ribera when it was offered for sale at a Madrid auction house in April 2021. But something about the painting and its luminous qualities led experts in Spain and Italy to re-examine the work.

Hope Hicks said last week Donald Trump told her Michael Cohen paid off Stormy Daniels to protect him from a false allegation

• Trump trial to resume after teary testimony from key aide Hope Hicks

Here is a look at some images from the Manhattan courthouse that came through the newswires last week:

With the trial entering its fourth week, here is a reminder of the key players by the Guardian’s Sam Levine:

Donald Trump , defendant: The Republican nominee for president is the defendant in the case. Prosecutors allege that he orchestrated a $130,000 payment to the adult film star Stormy Daniels when she threatened to go public with allegations of an affair on the eve of the 2016 election, and then conspired with others to cover up the payment.

David Pecker, key witness: Pecker was a key Trump ally who served as the CEO of American Media Inc (AMI), the publisher of the National Enquirer. Pecker helped Trump by purchasing the rights to potentially damaging stories and then never publishing them, a practice known as “catch and kill”.

Stormy Daniels, key witness: Daniels, an adult film star, says she met Trump in 2006 at a celebrity golf tournament. Daniels was 27 at the time and Trump was 60 and Daniels has always said the sex was consensual. Just before the 2016 election, Daniels said she was approached by Michael Cohen , Trump’s lawyer at the time, and offered $130,000 not to disclose the alleged affair.

Michael Cohen, key witness: Cohen was once a lawyer for Trump and one of the former president’s most loyal lieutenants and enforcers. He facilitated the payment to Daniels, funnelling the $130,000 to her through a shell company called Essential Consultants LLC. Trump later arranged to pay him back in monthly payment installments of $35,000.

Union says rise unwelcome for tourists and residents – but officials say holders of regular transport passes will not be affected

Paris’s public transport authority has been accused of initiating ‘a bit of a racket’ after raising the price of Métro tickets by more than 85% and doubling the cost of bus tickets during the Olympic and Paralympic Games this summer.

A single journey ticket in the Métro will rise from €2.15 to €4, while a ticket for a city bus will double from €2.50 to €5 from 20 July – six days before the Games begin – and remain until 8 September, the transport authority RATP has announced.

Exclusive: Mukhtar Babayev says clear accounting crucial to build trust as developing world seeks trillions in support

Poor countries must demonstrate clearer accounting and transparency to back up their calls for trillions of dollars of climate finance , the president of global climate negotiations has said.

Mukhtar Babayev, the ecology minister of Azerbaijan, who will lead the Cop29 UN climate summit in November, urged governments in developing countries to draw up reports showing their progress on cutting greenhouse gas emissions, and their spending on the climate crisis.

Researchers say more bodies of Herero and Nama people from early 20th century concentration camp could be in waters around port

The Namibian authorities are being urged to halt plans to extend a port on the Shark Island peninsula after the discovery of unmarked graves and artefacts relating to the Herero and Nama genocide.

Forensic Architecture , a non-profit research agency, said it had located sites of executions, forced labour, imprisonment and sexual violence that occurred when the island was used by the German empire as a concentration camp between 1905 and 1907.

Far-right congresswoman has spearheaded effort to oust fellow Republican as speaker but motion to vacate widely expected to fail

The House is expected to vote this week on a motion to remove Republican Mike Johnson as speaker, but the effort, spearheaded by hard-right congresswoman Marjorie Taylor Greene, faces virtually no chance of success.

Greene announced on Wednesday that she would move forward with forcing a vote on Johnson’s removal this week, following through on a threat she first issued in late March. Greene has consistently attacked Johnson for advancing bills that have attracted widespread bipartisan support, such as the government spending proposal approved in March and the foreign aid package signed into law last month.

Cezar Diaz’s sensitive and humane film looks back at one of the bloodiest periods of the Guatemalan civil war from the perspective of one damaged family

Here is a thoughtful, restrained drama about one of the bloodiest periods during the long civil war in Guatemala , fought between US-backed rightwing generals and leftwing insurgents. In the 1980s, thousands of men, women and children were killed, mostly by soldiers. Our Mothers starts as a straightforward drama about families, decades later, still looking for relatives who disappeared in the massacres. But what emerges is a sensitive and moving portrait of female survivors – the clue is in the title.

In 2018, Ernesto (Armando Espitia) is a hard-working young government forensic investigator. Director Cesar Diaz follows Ernesto with a low-key documentary-like style as the young man goes about his job locating mass graves and exhuming bodies. One day, an indigenous woman, Nicolasa (Aurelia Caal), walks into his office with a familiar story: more than 30 years ago, soldiers tortured and killed the men in her farming village, then raped the women. Diaz handles the accounts of sexual violence with tremendous sensitivity, giving no more information than needed.

Researchers say experimental shot is step towards goal of creating vaccines before a pandemic has started

Scientists have created a vaccine that has the potential to protect against a broad range of coronaviruses, including varieties that are not yet even known about.

The experimental shot, which has been tested in mice, marks a change in strategy towards “proactive vaccinology”, where vaccines are designed and readied for manufacture before a potentially pandemic virus emerges.
