France's interior minister has ordered local authorities to ban all pro-Palestinian demonstrations amid a rise in antisemitic acts since Hamas attacked Israel over the weekend.

President Emmanuel Macron urged French people not to allow the war in the Middle East erupt into tensions at home.

Soon before Macron spoke in a televised address to the nation about the conflict, Paris police used tear gas and water cannons to disperse pro-Palestinian protesters who had defied a ban and demonstrated on Thursday against the Israeli government.

''Let us not bring ideological adventures here (to France) by imitation or by projection,″ Macron pleaded.

"Let us not add national fractures … to international fractures.

''Let us stay united.″

With several French-Israeli citizens believed held hostage by Hamas, Macron pledged that France would protect its Jewish citizens and be ''ruthless toward all those who bear hate″, and noted concerns about hostility toward France's Muslims too.

Fighting in the Middle East in the past has led to tensions in France, which is estimated to have the world's third-largest Jewish population after Israel and the US, and the largest Muslim population in Western Europe.

Macron said that 13 French citizens in Israel have been killed in the current fighting, with 17 people missing, many believed held hostage by Hamas.

The Paris prosecutor's office opened an investigation Thursday into the killings and suspected kidnappings.

The French government has reported 24 arrests for more than 100 antisemitic acts in France since Hamas attacked Israel on Saturday, including verbal abuse, people caught with knives near Jewish schools and synagogues and a drone equipped with a camera spotted over a Jewish cultural centre.

More than 2000 cases of antisemitic speech have been reported to an online watchdog force.

Interior Minister Gerald Darmanin sent a directive to local prefects on Thursday, seen by The Associated Press, calling for a further tightening of security around Jewish schools, synagogues and other sites.

It said pro-Palestinian demonstrations should be banned and those who defy bans should be arrested, ''because they are susceptible to disrupt public order".

Pro-Palestinian associations decried the move.

The National Collective for a Fair and Lasting Peace between Palestinians and Israelis said it ''denounces this threat to freedom of expression,'' and pledged to continue holding actions to support the Palestinian people.

At the banned Paris protest on Thursday, protesters draped Palestinian flags around their shoulders, and ''Free Palestine'' was sprayed on the monument underpinning Republic Plaza in eastern Paris.

Many chanted "We are all Palestinians.''

Earlier this week, thousands of people marched in Paris in support of Israel, and the Eiffel Tower was lit up with a Star of David and the blue and white of the Israeli flag.

Other European cities have seen pro-Palestinian demonstrations in recent days as well as pro-Israeli gatherings.

Denouncing Hamas as a terrorist group, Macron called for peace efforts that would ensure both Israel's security and a Palestinian state.

''Those who confuse the Palestinian cause with justifying terrorism are committing a moral, political and strategic error,″ he said.

Macron also sought to address the concerns of French-Israeli families whose loved ones have disappeared and are believed kidnapped or killed by Hamas.

Struggling to speak as they sobbed or choked back tears, family members of missing French citizens pleaded Thursday at a news conference in Tel Aviv for help from Macron.

''We will do everything so that these hostages, regardless of their nationality, are freed,″ Macron said.

French Foreign Minister Catherine Colonna announced she would travel to the region on Sunday. France's government organized an evacuation flight Thursday to bring French citizens in Israel to Paris, and other flights are planned in the coming days.

The family of Israeli woman Moran Yanai is pleading for her safe return, after the 40-year-old was kidnapped fleeing an under-siege music festival in the country's south.

The jewellery designer had been invited to set up a retail stand at the Supernova Festival in southern Israel, which was stormed in a terrifying surprise attack by Hamas militants on Saturday.

More than 260 bodies have reportedly been recovered from the site outside Kibbutz Re'im.

Yanai's brother-in-law, former Underbelly actor Dan Mor, spoke to 9News from Tel Aviv, detailing how the family lost contact with her as she tried to flee.

"In the morning, around 7am she rang her father, saying that they're being shot at … And then I think at 8.30am she spoke to her mum, saying that they're hiding, they're being shot at," he said.

"Then we lost contact."

In a race for information as to Yanai's whereabouts and safety, the family reached out to authorities, and scoured social media.

Several hours later they were alerted to a video posted on an anonymous TikTok account, showing the 40-year-old begging for her life as militants are heard shouting.

This is the last her family heard from the woman they describe as a "peace-seeking loving artist" and a "pure soul".

They are channelling their anguish by calling on help from world leaders, in the hope she is brought home safely.

"I don't lose faith, we have faith. That's what I'm speaking to you," Mor said.

Mor is a dual-Australian citizen and would be eligible to apply for a government-backed repatriation flight, however he said he fears his family would not be safe in his old hometown of Sydney, where local leaders have condemned 'abhorrent' scenes of anti-Semitism.

"It's a nightmare that we have to wake up from," he said.

If you've been dreaming of buying a holiday home with waterfront views in Queensland, this could be the deal for you. 

Marketed as a once-in-a-lifetime bargain, apartments on island resort Couran Cove are being sold for prices as low as $50,000 but they do come with a catch.

The resort is closed and there is no power, water, gas or sewerage and no timeline for any of it to be switched back on.

A body corporate dispute led to the resort being completely cut off in June.

As a result, many residents and holidaymakers decided to sell up, leading to the record-low prices.

Critton Astras from Astras and Bond Estate Agents said buyers won't be able to find similar fully- urnished, freehold property on the water for "such a low price".

"From studios, one bedrooms, two-0bedroom lodges, three bedrooms, some great eco cabins out in the forest and you've got the villas," he said.

"Anything ranging from say $50,000 all the way through to $300,000."

While buyers are taking a risk, one resident said for him it was worth taking the chance.

"My wife and I came here a few years ago when it was sort of open, we sort of always loved the place and obviously it's a great time to buy now," unit owner Justin Daly said.

Daly is currently using generators and solar panels to keep the lights on and said he is remaining optimistic about the future. 

"People here are amazing," he said.

"They care about the place and I really think that it'll be what it was before."
