DEIR AL-BALAH, OCTOBER 27

Israel expects to launch a long and difficult ground offensive into Gaza soon to destroy Hamas, the country's defense minister said Friday, describing a campaign that will require dismantling a vast network of tunnels used by the territory's militant rulers.

Defense Minister Yoav Gallant spoke to a small group of foreign reporters in Tel Aviv after Israeli forces backed by fighter jets and drones carried out a second, limited ground raid into Gaza in as many days, striking the outskirts of Gaza City.

Gallant said the ground invasion that follows weeks of airstrikes 'will take a long time,' and that it would lead to another lengthy phase of lower-intensity fighting, as Israel destroys 'pockets of resistance.'

In a sign of rising tensions in the region, US warplanes struck targets in eastern Syria that the Pentagon said were linked to Iran's Revolutionary Guard after a string of attacks on American forces, and two mysterious objects hit towns in Egypt's Sinai Peninsula.

After three weeks of war sparked by a bloody Hamas incursion into southern Israel, the Palestinian death toll has soared past 7,300, according to officials in Gaza. A blockade on Gaza has meant dwindling supplies of food, fuel, water and medicine, and UN and Arab leaders have called for a cease-fire to allow entry of humanitarian aid that is only trickling in.

Gaza's Health Ministry on Thursday released a detailed list of names and identification numbers of those killed, including more than 3,000 minors and more than 1,500 women.

More than 1,400 people were slain in Israel during Hamas' Oct. 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 wars between Israel and Hamas, estimated at around 4,000. A ground invasion is expected to cause even higher casualties on both sides as Israeli forces and Hamas battle each other in dense residential areas.

Hospitals have been scrounging for fuel to run emergency generators that power incubators and other life-saving equipment after Israel cut off all fuel deliveries to Gaza at the start of the war, forcing its only power plant to shut down.

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 (miles) 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.

Little is known about Hamas' secretive tunnels and other infrastructure, and it wasn't possible to independently confirm Gallant's claims.

Lynne Hastings, the U.N. aid coordinator for the Palestinian territories, declined to comment on Gallant's remarks, saying 'we don't know what Hamas has or doesn't have.'

'We have been bringing fuel into Gaza in coordination with the government of Israel for decades. We know fuel is a high-risk item and are working with the Israelis to make sure what we will be using for our operations is done securely,' she said.

The UN agency for Palestinian refugees, which provides basic services to hundreds of thousands of people in Gaza, said it has been forced to ration fuel among lifesaving machines in hospitals, bakeries, and desalination plants, and only has enough for a few more days.

'The siege means that food, water and fuel – basic commodities - are being used to collectively punish more than 2 million people, among them, a majority of children and women,' Philippe Lazzarini, the head of UNRWA, told reporters.

Earlier on Friday, the military said ground forces raided inside Gaza, striking dozens of militant targets over the past 24 hours. It said aircraft and artillery bombed targets in Shijaiyah, a neighborhood on Gaza City's outskirts that was the scene of an urban battle in the 2014 Gaza war.

The military said the soldiers exited the territory without suffering any casualties. It reported an earlier, hourslong raid into northern Gaza on Thursday.

The damage to Gaza from nearly three weeks of bombardment showed in satellite photos of several locations taken before the war and again in recent days. Entire rows of residential buildings simply disappear in the photos, reduced to smears of dust and rubble.

The Israeli military says it only targets militants and accuses Hamas of operating among civilians in an attempt to protect its fighters.

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

US Defense Secretary Lloyd Austin said that the Friday strikes in eastern Syria were a response to 'ongoing and mostly unsuccessful attacks' against US personnel in Iraq and Syria over the past 10 days. He said the operation was separate from the Israel-Hamas war.

Hezbollah, an Iranian-backed ally of Hamas in Lebanon, has repeatedly traded fire with Israel along the border, and Israel has carried out airstrikes targeting Iran-linked groups in Syria. The United States has sent two aircraft carrier strike groups to the region, along with additional weaponry and personnel, in part to deter Iran and its allies from entering the war.

Egypt's military meanwhile said a drone crashed into a building in the Red Sea town of Taba, on the border with Israel, slightly wounding six people. In a separate incident, the state-run Al-Qahera news said a 'strange object' landed near a power station in the Red Sea town of Nuweiba, further south. Footage showed debris and smoke rising from the side of a nearby mountain.

Last week, a US Navy destroyer in the northern Red Sea shot down three cruise missiles and several drones launched toward Israel by Iran-backed Houthi rebels in northern Yemen.

About 1.4 million of Gaza's 2.3 million residents have fled their homes, with nearly half of them crowding into UN shelters. Hundreds of thousands remain in northern Gaza, despite Israel ordering them to evacuate to the south and saying that those who remain might be considered 'accomplices' of Hamas.

Over the past week, Israel has allowed more than 80 trucks with aid enter from Egypt through the Rafah crossing, the only entry point into Gaza not controlled by Israel. But aid workers say the convoys meet only a tiny fraction of the territory's mounting humanitarian needs. Before the war, an average of 500 trucks entered Gaza each day, according to the United Nations.

The Palestinian Red Crescent said on social media that it had received 10 trucks of food, medicine and other supplies had passed through Rafah on Friday morning.

The US has been working with other mediators to send in more humanitarian aid, but Israel is insisting on strict screening procedures for all trucks that enter. Hundreds of foreign passport holders are trying to leave Gaza, but the U.S. says Hamas has refused to allow that.
