Doctors Without Borders warned Friday that its teams on the ground in Gaza were witnessing surging levels of acute malnutrition in the besieged and war-ravaged Palestinian territory.

The medical charity, known by its French acronym MSF, said levels of acute malnutrition had reached an "all-time high" at two of its facilities in the Gaza Strip.

"MSF teams are witnessing a sharp and unprecedented rise in acute malnutrition among people in Gaza," the organisation said in a statement.

Yemen's Huthi rebels have resumed their attacks on Red Sea shipping, saying they aim to force Israel to cease fire in Gaza -- a move that threatens a truce with Washington and rattles maritime trade.

The Iran-backed rebels allege that the two vessels they attacked earlier this week -- the Magic Seas and the Eternity C -- were linked to trade with Israel.

But their renewed campaign comes at a pivotal moment when Washington and Tehran are weighing talks following a devastating 12-day Iran-Israel war, while Hamas and Israel are holding truce negotiations in Qatar.

Nearly 800 people have died trying to access aid in Gaza since late May, with most killed near the US- and Israel-backed Gaza Humanitarian Foundation's sites, the UN said Friday.

An officially private effort, the Gaza Humanitarian Foundation (GHF) began operations on May 26 after Israel halted supplies into the Gaza Strip for more than two months, sparking warnings of imminent famine.

Since those operations began and through July 7, United Nations rights office spokeswoman Ravina Shamdasani said the agency had recorded "615 killings in the vicinity of the GHF sites".

Ten Palestinians were reported killed Friday waiting for rations in Gaza, adding to the nearly 800 killed seeking aid in the last six weeks, according to the UN, with Israel's army saying it issued troops new instructions following the repeated reports of deaths.

Friday's violence came as negotiators from Israel and the Palestinian militant group Hamas were locked in indirect talks in Qatar to try to agree on a temporary ceasefire in the more than 21-month conflict.

Iranian activist Narges Mohammadi, who won the 2023 Nobel Peace Prize for her fight for women's and human rights in Iran, has received death threats from Tehran, the Nobel Committee said Friday.

Mohammadi, who has spent much of the past decade behind bars, was released from Tehran's Evin prison in December for a limited period on medical leave, with her legal team repeatedly warning that she could be re-arrested at any time.

Gaza's civil defence agency said Israeli forces killed at least 30 people on Friday, including 10 who were waiting for aid in the south of the war-ravaged territory.

The latest deaths came as the United Nations said nearly 800 people had been killed trying to access food in Gaza since late May, when Israel began easing a more than two-month blockade on deliveries.

UN human rights office spokeswoman Ravina Shamdasani said most of the deaths occurred near facilities operated by the US- and Israel-backed Gaza Humanitarian Foundation.

Thirty PKK fighters destroyed their weapons at a symbolic ceremony in Iraqi Kurdistan on Friday, two months after the Kurdish rebels ended their decades-long armed struggle against the Turkish state.

The ceremony marked a major step in the transition of the Kurdistan Workers' Party (PKK) from armed insurgency to democratic politics as part of a broader effort to end one of the region's longest-running conflicts.

Whether dining opposite US President Donald Trump or accompanying her husband on an official Pentagon visit, Sara Netanyahu's front-row role in Washington this week has sparked fresh questions over her place in Israeli politics.

Prime Minister Benjamin Netanyahu's third wife and the mother of two of his children, Sara Netanyahu has long made headlines, notably for her alleged involvement in the political decisions of her husband.

Syrian couturier Rami Al Ali made history Thursday as the first fashion designer from his country to feature in the official Paris Haute Couture Week calendar in a new landmark for Arab representation in the luxury business.

After years of showing his tailored evening dresses on the sidelines of Couture Week, he was invited this year by France's Federation de la Haute Couture et de la Mode to join the programme.

A UK parliamentary committee on Thursday blamed Iran for at least 15 attempts to kill or kidnap British-based individuals since 2022, saying the threat from Iran had "significantly increased".

London's response has been too focused on "crisis management", said parliament's intelligence and security committee, with concerns over Iran's nuclear programme dominating their attention too much.

Tehran swiftly issued a "categorical rejection of the unfounded, politically motivated and hostile allegations".
