Protests have been held across the country today calling for an immediate ceasefire.

Israel knocked out internet and communications in the Gaza Strip in stepped-up bombardment on Friday night, largely cutting off its 2.3 million people from contact with each other and the outside world and creating a near-blackout of information, as the military said it was "expanding" ground operations in the territory.

The military's announcement signaled it was moving closer to an all-out invasion of Gaza, where it has vowed to crush the ruling Hamas militant group after its bloody incursion in southern Israel three weeks ago.

Explosions from continuous airstrikes lit up the sky over Gaza City for hours after nightfall.

The Palestinian telecommunications provider, Paltel, said the bombardment caused "complete disruption" of internet, cellular and landline services.

The cutoff meant that casualties from strikes and details of ground incursions could not immediately be known. Some satellite phones continued to function.

Already plunged into darkness after most electricity was cut off weeks ago, Palestinians were thrown into isolation, huddling in homes and shelters with food and water supplies running out.

Relatives outside Gaza panicked after their messaging chats with families inside suddenly went dead and calls stopped going through.

"I was so scared this was going to happen," said Wafaa Abdul Rahman, director of a feminist organisation based in the West Bank city of Ramallah. She said she hadn't heard for hours from family in central Gaza.

"We've been seeing these horrible things and massacres when it's live on TV, so now what will happen when there's a total blackout?" she said, referring to scenes of families that have been crushed in homes by airstrikes over the past weeks.

Israeli military spokesman Rear Admiral Daniel Hagari said ground forces were "expanding their activity" Friday evening in Gaza and "acting with great force… to achieve the objectives of the war."

Israel says its strikes target Hamas fighters and infrastructure and that the militants operate from among civilians, putting them in danger.

The Hamas media center reported heavy nighttime clashes with Israeli forces at several places, including what it said was an Israeli incursion east of Bureij.

Asked about the report, the Israeli military reiterated early Saturday that it had been carrying out targeted raids and expanding strikes with the aim of "preparing the ground for future stages of the operation."

Israel has amassed hundreds of thousands of troops along the border ahead of an expected ground offensive.

Earlier Friday the military said ground forces conducted their second hours-long incursion inside Gaza in as many days, striking dozens of militant targets over the past 24 hours.

The Palestinian death toll in Gaza has soared past 7300, more than 60 per cent of them minors and women, according to the territory's Health Ministry.

A blockade on Gaza has meant dwindling supplies, and the UN warned that its aid operation helping hundreds of thousands of people was "crumbling" amid near-depleted fuel.

More than 1400 people were slain in Israel during Hamas' October 7 attack, according to the Israeli government, and at least 229 hostages were taken into Gaza.

Palestinian militants have fired thousands of rockets into Israel, including one that hit a residential building in Tel Aviv on Friday, wounding four people.

The overall number of deaths far exceeds the combined toll of all four previous Israel-Hamas wars, estimated at around 4000.

Defence Minister Yoav Gallant said Israel expects a long and difficult ground offensive into Gaza soon.

It "will take a long time" to dismantle Hamas' vast network of tunnels, he said, adding that he expects a lengthy phase of lower-intensity fighting as Israel destroys "pockets of resistance."

His comments pointed to a potentially grueling and open-ended new phase of the war after three weeks of relentless bombardment.

Israel has said it aims to crush Hamas' rule in Gaza and its ability to threaten Israel.

But how Hamas' defeat will be measured and an invasion's endgame remain unclear. Israel says it does not intend to rule the tiny territory but not who it expects to govern — even as Gallant suggested a long-term insurgency could ensue.

In Washington, the Pentagon said US Defence Secretary Lloyd Austin spoke with Gallant on Friday and "underscored the importance of protecting civilians during the Israel Defence Forces' operations and focusing on the urgency of humanitarian aid delivery for civilians in Gaza."

The Pentagon said Austin also brought up "the need for Hamas to release all of the hostages."

The conflict has threatened to ignite a wider war across the region.

Arab nations — including US allies and ones that have reached peace deals or normalised ties with Israel — have raised increasing alarm over a potential ground invasion, likely to bring even higher casualties amid urban fighting.

Jordanian Foreign Minister Ayman Safadi warned on X that the "outcome will be a humanitarian catastrophe of epic proportions for years to come."

With no electricity, no communications and no water, many of those trapped in Gaza had little choice but to wait in their homes or seek the relative safety of schools and hospitals as Israel expanded its bombing early on Saturday.

Throughout the night, orange fireballs exploded on the horizon above the apartment buildings and refugee camps of Gaza City, briefly illuminating clouds of white smoke hanging in the air from previous strikes.

Some bombs hit in tight groups, apparently slamming into the same location.

Lynn Hastings, UN humanitarian coordinator for the occupied territories, posted on X, formerly known as Twitter, that without phone lines and internet, hospitals and aid operations would be unable to operate.

The Red Crescent said it could not contact medical teams and residents could no longer call ambulances, meaning rescuers would have to chase the sound of explosions to find the wounded.

International aid groups said they were only able to reach a few staffers using satellite phones.

The Committee to Protect Journalists expressed alarm, saying the world "is losing a window into the reality" of the conflict.

It warned that the information vacuum "can be filled with deadly propaganda, dis- and misinformation."

The loss of internet and phones deals a further blow to a medical and aid system that relief workers say was already on the verge of collapse.

More than 1.4 million people have fled their homes, nearly half crowding into UN schools and shelters.

Aid workers say a trickle of aid Israel has allowed to enter from Egypt the past week is a tiny fraction of what is needed.

Gaza hospitals have been scrounging for fuel to run emergency generators that power incubators and other life-saving equipment.

Gallant said Israel believes that Hamas would confiscate any fuel that enters. He said Hamas uses generators to pump air into its hundreds of kilometers of tunnels, which originate in civilian areas.

He showed reporters aerial footage of what he said was a tunnel shaft built right next to a hospital.

"For air, they need oil. For oil, they need us," he said.

Late Friday the army released photos showing what it said were Hamas installations in and around Gaza City's Shifa Hospital, Gaza's largest.

Israel has made such claims before, but declined to say how the photos were obtained.

Little is known about Hamas' tunnels and other infrastructure. Claims by the military and Gallant couldn't be verified.

Speaking at Shifa Hospital, Hamas media chief Salama Maroof called Israel's claims "lies" and said they were "a precursor for striking this facility."

"I ring the alarm bell. There is imminent danger hovering above the medical facility," Maroof said.

The hospital has been overwhelmed and around 40,000 displaced residents have crowded its grounds for shelter, the UN says.

Asked if Israel plans to target Shifa, Hagari said, "We will not be able to allow terror activity against Israel from hospitals."

Hundreds of thousands of people remain in northern Gaza.

The US Army reservist accused of killing 18 people and injuring 13 more in a shooting rampage across a small Maine city this week is dead from an apparent self-inflicted gunshot wound to the head, multiple sources tell CNN.

Robert Card, 40, was found dead in the woods near Lisbon, some 8 miles from Lewiston, where Wednesday's shooting happened, the same sources said.

This follows a two-day manhunt that prompted shelter-in-place-orders and the shutdown of schools and businesses as law enforcement furiously pursued him after Wednesday's attack at a bowling alley and a restaurant in Lewiston.

The attack was the deadliest US mass shooting since last year's massacre at a school in Uvalde, Texas.

Maine State Police plan to hold a news conference soon.

The gun investigators believe Card used to carry out the massacre was purchased legally just days before he was hospitalised and ordered to undergo a psychiatric evaluation, according to multiple law enforcement sources.

In mid-July, New York State Police were called to Camp Smith in Cortlandt, New York, the military base where Card served, because he was acting "belligerently and possibly intoxicated," according to a source briefed on the matter.

Three law enforcement sources confirm State Police brought Card to a nearby hospital, where he was treated for suspected intoxication and released the next day.

When asked for information about the encounter, a New York State Police spokesperson told CNN: "This is an active investigation, and the New York State Police does not comment on active investigations."

A federal law enforcement source told CNN the army gave Card a "Command Referral" to seek treatment after he told army personnel at Camp Smith Card had been "hearing voices" and had thoughts about "hurting other soldiers."

A National Guard spokesperson confirmed to CNN Card was transported to the nearby Keller Army Community Hospital at the United States Military Academy for "medical evaluation," after Army Reserve officials reported Card for "behaving erratically."

Card's encounters with New York State Police and his National Guard superiors occurred just 10 days after Card had purchased the high-powered rifle at a Maine gun store, according to law enforcement sources.

The rifle was a Ruger SFAR chambered for high-powered .308 ammunition, the sources added. The .308 round is favoured by military snipers firing at long distances and big game hunters.

It is larger and more powerful than the regular ammunition carried in the rifles of soldiers and SWAT teams.

Sources say the weapon found inside Card's 2013 white Subaru Outback appears to be the same one fired by the gunman at the bowling alley and a local bar, though a ballistics match has not been confirmed.

The weapon will be processed by the FBI and ATF for fingerprints and DNA and then run through laboratory testing to determine if the bullets and shell casings found at the scene match.

In the same July purchase, along with the rifle, sources say Card also bought a Beretta 92-F 9mm semi-automatic pistol. It is the standard pistol of the US military.
