BEIRUT (Reuters) -Hundreds of people protested in southern Lebanon on Wednesday against a planned visit by U.S. envoy Thomas Barrack, a day after the envoy stirred anger in the country by publicly scolding Lebanese reporters.

Lebanon's state news agency said Barrack's visit to Tyre and the border town of Khiyam had been cancelled due to the demonstrations. Protesters carried banners reading "Death to America" and waved the flags of Iran-backed militant group Hezbollah and its Shiite ally, the Amal movement, according to social media footage and witnesses.

The head of Save the Children described in horrific detail Wednesday the slow agony of starving children in Gaza, saying they are so weak they do not cry.

Addressing a UN Security Council meeting on the Israeli-Palestinian conflict, the president of the international charity, Inger Ashing, said famine -- declared by the UN last week to be happening in Gaza -- is not just a dry technical term.

"When there is not enough food, children become acutely malnourished, and then they die slowly and painfully. This, in simple terms, is what famine is," said Ashing.

Israel on Wednesday called on UN-backed hunger monitor the Integrated Food Security Phase Classification Initiative (IPC) to immediately retract a report which determined that famine was present in parts of Gaza.

"Israel demands that the IPC will retract immediately its fabricated report and publish a notice," the director general of Israel's foreign ministry, Eden Bar Tal, told a press conference.

He said Israel would share "evidence" of misconduct in preparing the report with IPC's donors if the organisation fails to heed "within a short time".

PARIS/DUBAI (Reuters) -Britain, France and Germany are likely to begin the process of reimposing U.N. sanctions on Iran on Thursday, but hope Tehran will provide commitments over its nuclear programme within 30 days that will convince them to defer concrete action, four diplomats said.

The trio, known as the E3, met Iran on Tuesday to try to revive diplomacy over the nuclear programme before they lose the ability in mid-October to restore sanctions on Tehran that were lifted under a 2015 nuclear accord with world powers.

Iran said Wednesday that the return of UN nuclear inspectors did not represent a full resumption of cooperation, which was suspended in the aftermath of June attacks by Israel and the United States.

Inspectors from the International Atomic Energy Agency began work at the key nuclear site of Bushehr in southwestern Iran, the nuclear watchdog's chief Rafael Grossi said, the first team to enter the country since Tehran formally suspended cooperation with the UN agency last month.

DUBAI (Reuters) -UN nuclear inspectors have returned to Iran for the first time since it suspended cooperation with them in the wake of Israel's attacks on its nuclear sites, Iranian state media reported on Wednesday.

Iranian Foreign Minister Abbas Araqchi told lawmakers Tehran had still not reached an agreement on how it would resume full work with the UN's IAEA watchdog, parliament news agency ICANA reported.

But he said the inspectors would supervise the changing of fuel at Iran's Bushehr nuclear power plant, according to the report.

ROME (Reuters) -Italian Prime Minister Giorgia Meloni said in a speech on Wednesday that her government condemned the "unjustifiable" killing of journalists in Gaza.

Israel struck Nasser Hospital in the south of the Gaza Strip on Monday, killing at least 20 people, including five journalists who worked for Reuters, the Associated Press, Al Jazeera and others.

"It is an unacceptable attack on press freedom and on all those who courageously risk their lives to report on the tragedy of war," she said during a political conference in the beach town of Rimini.

Oscar-winning Spanish director Pedro Almodovar urged Madrid to cut all diplomatic and commercial ties with Israel Wednesday over the war in Gaza, calling the conflict a "genocide".

The "All About My Mother" director called on Spanish Prime Minister Pedro Sanchez to convince other European leaders to do the same in a video posted on Instagram by his production company.

Lebanese state media said US envoy Tom Barrack cut short a visit to the south on Wednesday, amid protests in two planned stops against US pressure to disarm Hezbollah.

The official National News Agency (NNA) reported that Barrack arrived by helicopter at a Lebanese army barracks in Marjayoun near the border, with soldiers deploying in the area.

The news agency later reported that the envoy had cancelled planned stops in nearby Khiam, which was pummelled by Israel during its latest hostilities with Hezbollah, and in the coastal city of Tyre.

Dozens of Israeli soldiers stormed the occupied West Bank city of Nablus on Wednesday, witnesses and Palestinian officials said, with the Red Crescent reporting at least seven people wounded in the raid.

Contacted by AFP, the Israeli military confirmed that its forces were conducting an operation in the northern West Bank city, without specifying its purpose.

The raid began at around 3:00 am (0000 GMT), residents said, with soldiers in armoured vehicles storming several neighbourhoods of Nablus's old city, which has a population of around 30,000 people.
