Thousands of pro-Palestinian demonstrators marched through central London to the United States embassy on Saturday to protest against President Donald Trump's proposal that the US "take over" Gaza.

Waving Palestinian flags and placards saying "Hands off Gaza," several thousand people walked from Whitehall in Westminster over the River Thames to the embassy in Nine Elms.

Earlier this month, Trump stunned the world when he suggested the US could redevelop the war-ravaged Gaza Strip into the "Riviera of the Middle East".

As Palestinian inmates released by Israel on Saturday stepped off the buses that took them to the Gaza Strip, some flashed a victory sign and swiftly set fire to sweatshirts they were made to wear in prison.

Images broadcast on Israeli media before their release under a ceasefire deal with Hamas showed rows of Palestinian prisoners wearing the sweatshirts emblazoned with the Star of David, the logo of Israel's prison service and the Arabic phrase "we do not forget and we do not forgive".

Through tears and tight embraces, freed Israeli-American hostage Sagui Dekel-Chen on Saturday finally learnt the name of his youngest daughter, born two months after he was abducted by Gaza militants in October 2023.

In footage published by the Israeli government, Dekel-Chen's wife Avital, shedding tears of joy as the two embraced after 16 months apart, told him that the baby girl was named Shahar Mazal, which could translate into "lucky dawn" in English.

"That's perfect," the 36-year-old responded, moments after he was brought back to Israel.

The UK government on Saturday named two Britons detained in Iran as Craig and Lindsay Foreman, with their family saying they are determined to ensure the pair's "safe return".

The two are currently being held in Kerman, a city and province in southeast Iran, the family said in a statement issued by the British foreign ministry.

"This unexpected turn of events has caused significant concern for our entire family, and we are deeply focused on ensuring their safety and well-being during this trying time," they said.

Holding up signs reading "sorry and welcome back" and "complete the ceasefire", hundreds of Israelis gathered in Tel Aviv's "Hostages Square" on Saturday to watch Hamas release three Israeli hostages from Gaza.

In smaller groups, friends and relatives of the released men -- Israeli-American Sagui Dekel-Chen, 36, Israeli-Russian Sasha Trupanov, 29, and Israeli-Argentine Yair Horn, 46 -- shed tears of joy at the sight of their loved ones, who were made to address a crowd in Gaza from a stage alongside rifle-wielding militants.

Their voices monotone and their faces staring mostly ahead, three Israeli hostages spoke in Hebrew on a Gaza stage before walking to freedom on Saturday, after more than 16 months of captivity in the Palestinian territory.

The carefully choreographed handover to the Red Cross in Gaza came as part of an ongoing ceasefire deal with Israel.

Compared to three emaciated captives released last week, Israeli-American Sagui Dekel-Chen, Israeli-Russian Sasha Trupanov and Israeli-Argentine Yair Horn appeared in better health as they emerged from a white car.

A bus carrying a group of Palestinian prisoners released Saturday by Israel under the Gaza ceasefire deal arrived to a cheering crowd in the occupied West Bank city of Ramallah, according to an AFP journalist.

Wearing traditional keffiyeh scarves, the freed prisoners were hoisted onto the crowd's shoulders. They hugged relatives before heading to a quick health checkup, the journalist reported.

Many in the crowd waved yellow flags of the Fatah movement which dominates the Palestinian Authority, while one prisoner kissed a baby as soon as he stepped off the bus.

Lebanese authorities said Saturday that more than 25 people have been arrested following an attack on a United Nations convoy that wounded two peacekeepers, including the force's outgoing deputy commander.

UN and Lebanese officials have condemned Friday's attack, which came as Hezbollah supporters blocked the road to the country's only international airport for a second night over a decision to bar two Iranian flights from landing.

Palestinian militants released three Israeli hostages on Saturday in exchange for hundreds of Palestinian inmates freed by Israel, completing the latest swap despite fears the Gaza truce deal was near collapse.

An AFP journalist saw masked Hamas gunmen parade the hostages on a stage in Gaza's southern city of Khan Yunis.

Lebanese authorities are set to hold an emergency meeting on Saturday after a deputy commander with the UN peacekeeping force in the country was injured during an attack on a convoy taking him to the airport.

Hezbollah supporters have been blocking the road to the country's only airport for two consecutive nights over a decision barring two Iranian planes from landing in Beirut.
