Good morning.

The Israeli military admitted on Wednesday its troops had opened fire on a car carrying five-year-old Hind Rajab and six family members in Gaza in 2024, saying it had ordered a criminal investigation into the killing.

The death of Hind and her family was one of the most high profile of a series of incidents involving the killings of civilians during the first months of Israel’s war on Gaza, and it led to international outrage.

Hind died after a desperate three-hour phone call to the Palestinian Red Crescent on 29 January 2024 in which she pleaded for rescue. The family’s Kia Picanto car had been hit as the family sought to flee a new Israeli offensive into Gaza City. All the other passengers were also killed. Their bodies were retrieved 12 days later when Israeli troops withdrew.

• What prompted the investigation? The Israel Defense Forces repeatedly denied its troops had been in the area, but investigations by the media and others found evidence that strongly suggested nearby Israeli tanks were responsible.

• How significant is it? The IDF published reviews on Wednesday into five high-profile incidents in Gaza. But criminal misconduct investigations into Israeli troops over the killing of Palestinians rarely lead to convictions. A UN report published in February described “a pervasive climate of impunity” by Israel in occupied Palestine.

• What is the wider context? In September last year, a UN commission found that Israel is committing genocide in Gaza, citing tens of thousands of civilian deaths and massive destruction.

Meta has taken a “don’t ask, don’t tell” strategy when it comes to the safety of children on its social media platforms, according to a whistleblower who testified during a landmark trial against the company on Tuesday and Wednesday.

Arturo Béjar, a former Meta safety engineer, told the jury that the company was aware of the harm its products caused children, which included its recommendations pushing content from sexual predators and violent and graphic images. He said he repeatedly raised the issue to Facebook and Instagram executives but they did little to resolve it.

• What did Béjar say in his testimony? That his job often included him briefing Meta’s chief executive, Mark Zuckerberg, on product issues. He estimated that he spoke to Zuckerberg at least 100 times. One email Béjar sent to Zuckerberg in 2021 showed the engineer warning of constant reports of harmful content and damage to teenage wellbeing on Facebook and Instagram. Béjar said he emailed Zuckerberg after the chief executive publicly said the company did not prioritize profit over safety. Meta denies all allegations in the case.

Another democratic socialist victory sends shockwaves through party establishment

Democratic socialist Angie Nixon emerged a surprise victor in the US Senate primary on Tuesday, after a campaign in which she was outfunded and outspent by Alexander Vindman at a ratio of more than 10 to one.

Her triumph sent shockwaves through the Democratic party machine. There have been a series of primary wins for progressive candidates this summer, including in Philadelphia, Colorado, Michigan and New York City. Nixon only recently joined the Democratic Socialists of America, and was not endorsed by them.
