Authorities in Iran ordered schools and offices in at least 10 provinces to close on Sunday to conserve energy amid a severe cold snap and heavy snowfall, state media reported.

Freezing temperatures have gripped the northern half of the country over the past few days, causing a spike in energy consumption.

"All government offices and schools are closed on Sunday, and remote learning has been arranged for students," the state news agency IRNA announced.

Among the provinces affected are Lorestan in the west, Semnan in the east and Gilan in the north.

Prime Minister Benjamin Netanyahu on Sunday praised a proposal from President Donald Trump for US control of Gaza and the displacement of its population as "revolutionary", striking a triumphant tone in a statement to his cabinet following his return to Israel from Washington.

Trump set out a plan earlier this week to move the Gazans out of the territory to other countries in the region, while the United States would take charge of redeveloping it, sparking a diplomatic backlash.

The families of Thai farm workers held hostage in Gaza for over a year wept with joy and hugged their loved ones as they arrived in Bangkok on Sunday.

The five Thais smiled as they walked into the arrivals hall at Bangkok's Suvarnabhumi Airport after being freed on January 30, as part of a ceasefire deal aimed at ending the Gaza war.

He has no foreign policy experience but sports a reputation as a talented negotiator unafraid to speak his mind. And Donald Trump's special Middle East envoy Steve Witkoff has already made his mark.

A close friend to the US president, 67-year-old real estate magnate Witkoff is credited with playing a key role in negotiating the ceasefire in Gaza between Israel and the Hamas armed group.

The truce took effect January 19, on the eve of Trump's inauguration for a second term in the White House.

Several thousand Iranians came from across Europe to rally in Paris on Saturday, calling on world leaders to put greater pressure on the Islamic republic's ruling clerics.

"Instead of appeasing the mullahs, (the international community) should stand side by side with the Iranian people," Maryam Rajavi, president of the National Council of Resistance of Iran (NCRI), told the rally.

The NCRI is the political wing of the People's Mujahedin of Iran, which Tehran regards as a "terrorist" group.

More than 100 Palestinians freed into Gaza on Saturday returned to the territory to find it rendered unrecognisable by 15 months of war, while for many the fate of their loved ones was unknown.

"How is my family? Are they still alive?" one prisoner asked, calling out from a bus window as prisoners arrived in Khan Yunis in the southern Gaza Strip.

"Have there been martyrs in my family?" he shouted again before a voice in the crowd responded.

"They are all ok," came the reply.

Fakhri Barghouti grimaced in pain as an exultant crowd lifted him onto their shoulders next to his son Shadi, released from an Israeli jail on Saturday under a Gaza ceasefire deal.

Though Barghouti, 71, shed tears of joy at seeing his son, he was also in physical pain.

The night before, Israeli forces stormed his family home in the occupied West Bank village of Kobar, warning him not to celebrate his son's release and assaulting him, he said.

"They entered after midnight, smashed everything, took me into a side room and beat me before leaving," Barghouti told AFP.

Sony PlayStation's online services came back online on Saturday, the Japanese group said, after a 24-hour outage frustrated gamers around the world.

PlayStation Network "has been restored. You should be able to access online features without any problems now," said a statement on X around midnight GMT Sunday, 24 hours after a message acknowledged users were experiencing "difficulty launching games, apps or network features."

"Sorry for the inconvenience!" the post added, without providing further details on the reasons for the outage.

Israel's "lack of commitment" is putting the Gaza ceasefire in danger of collapse, a senior Hamas official told AFP on Saturday with talks yet to start on its second phase.

In an interview with AFP, Hamas political bureau member and former Gaza health minister Basem Naim warned the deal was in danger, but said the Palestinian militant group did not want to return to war.

The fifth release of Israeli hostages and Palestinian prisoners took place on Saturday, about halfway through the six-week first phase of the ceasefire deal.

Unexploded bombs and shells buried in the ruins of Gaza could kill or injure thousands of people in the war-ravaged Palestinian territory in the future, an aid organisation has warned.

The volume of ordnance dropped on Gaza during 15 months of conflict between Israel and the Palestinian militant group Hamas was "mind-boggling", said Simon Elmont, a demining expert with Handicap International - Humanity & Inclusion.
