The Israeli army is The besieged Gaza Strip.
The offensive stemmed from the back of Gaza's general blockade against Gaza after Israel decided to unilaterally end the ceasefire with Hamas.
Israel has suffered increasing international pressure, including from firm allies of the U.S. government that agree to a ceasefire and allow Gaza aid.
Meanwhile, Hamas and Israeli negotiators are holding new indirect negotiations in Doha.
Here is all you need to know about the latest ground attacks in Israel:
Operation Gideon's tanks were a major ground offensive launched by Israel in the Gaza Strip, killing hundreds of Palestinians in air strikes and further debilitating Gaza's healthcare network. With support from Israel's deadly air force, the operation targets Gaza in the south and north.
The attack began the day after the ceasefire between Israel and Hamas and ended in Doha on Saturday. Israel tends to strengthen operations and attacks in such negotiations. It said the latest offense is putting "tremendous pressure" on Hamas.
Israeli Prime Minister Benjamin Netanyahu launched the latest attack as U.S. President Donald Trump ruled that he was going to tour the Middle East against Saudi Arabia, Qatar and the United Arab Emirates, but did not stop in Israel.
The Israeli military said it launched an offensive to expand "operational control" in the Gaza Strip.
Israel said its campaign also aims to free the rest of the captives held by Gaza and defeat Hamas.
However, Netanyahu was criticized by a part of Israeli society, including the captured family, for failing to return with priority and rejected Hamas' proposal to end the war and release the prisoners.
A week before the operation, Netanyahu leaked the offer, talking about forced displacement of Palestinians in the Gaza Strip outside the Gaza Strip.
"We are destroying more and more houses," Netanyahu said in a closed testimony in the MP's diplomatic and defense committee. "The only inevitable result will be Gaza people's desire to migrate outside the Gaza Strip."
Israel has confirmed the operation since Sunday, with at least 144 people killed during a strike. At least 42 people died in severe bombings north of the street, according to medical sources. The five killed were journalists.
In southern Gaza, at least 36 people were killed in Israeli air strikes in Israel and injured in a tent camp of displaced Palestinians in the al-mawasi area of Khanyunes province, according to medical sources.
However, the operation's proposal also includes heavy attacks.
Over the past week, Israel has attacked more than 670 places in Gaza and claims that all are “Hamas targets” located above and below the ground. Israel has been accused of accusing civilians in Gaza, including displaced families. At least 370 Palestinians were killed in five days.
According to Gaza's Ministry of Health, at least 53,339 Palestinians have been killed and 121,034 injured since the war began in October 2023.
Recent Severity The attack has left many Palestinians expressing concerns on social media that their latest post might be their last one.
On Monday, the Israeli army issued a forced evacuation order to Khan Younis, Gaza's second largest city, warning of "an unprecedented attack."
Israel said it was targeting Hamas targets, an claim that it was increasingly challenged by human rights groups and experts as its 19-month war on Gaza continues.
Popular locations include hospitals, a recurring target of the Israeli army in Gaza. Gaza Hospital Director-General Muhammad Zaqout described the strategy as part of “a systematic Israeli measure against hospitals.”
Indonesian hospitals in northern Gaza were nonprofited after Israeli forces siege on Sunday. This could result in the deaths of thousands of patients and injured people, medical professionals said.
Marwan al-Sultan, the agency's director, described the situation as "disastrous", and he also called on international organizations to promote the safety of medical teams.
Al-Awda Hospital in Jabalia in northern Gaza and European Gaza Hospital in southern Gaza were also bombed.
In recent days, Israel said it had killed the late Yahya Sinwar's brother and successor Mohammad Sinwar and killed Hamas' leader. It also reportedly killed another Singwa brother, university lecturer Zakaria Sinwar, whose three children were in an air strike in central Gaza.
Hamas issued a statement on Sunday calling the attack on the displaced Palestinians in Khan Yunis a "brutal crime" and blatantly violated international laws and norms.
The group also blames the United States for supporting Israel.
“By granting political and military cover to the terrorist occupation government, the U.S. government is directly responsible for this crazy escalation of innocent civilians in the Gaza Strip, including children, women and the elderly,” Hamas said.
The entire strip has the risk of famine.
Israel has blocked basic humanitarian supplies, including food, fuel, medical assistance and children's vaccines, and cannot access the strip. More than 90% of the population has been displaced since the war began on October 7, 2023. Many Palestinians have been displaced multiple times, and some have been forced to relocate 10 times or more.
Israel has refused entry into any aid since March 2. International actors and institutions have been urgently demanding that Israel resume distributions of aid to Gaza to Gaza.
"Two months after the latest lockdown, 2 million people starved to death, while 116,000 tons of food were blocked at the border," WHO head Tedros Adhanom Ghebreyesus said in a speech at the opening ceremony of the annual World Health Organization.
According to the United Nations, one in five Palestinians in Gaza are currently facing hunger, and 9,000 children most vulnerable to Israel's ongoing food lockdown have been hospitalized for acute malnutrition since the beginning of the year.
Later on Sunday, Netanyahu announced that it would allow some food to enter the Canadian Belt to be requested local residents.
"Israel will provide basic food to the population to ensure there is no hunger crisis in the Gaza Strip," the Netanyahu office said in a statement.
Netanyahu said on Monday the move was motivated by pressure from Israeli allies.
It is not clear when the border will open to allow aid.
The latest talks began on Saturday and ended on Sunday with little progress.
Talks are scheduled to continue this week.
Both Israel and Hamas claim that negotiations begin with no conditions.
"The Hamas delegation outlined the stance of the group and the need to end the war, exchange prisoners, Israel evacuated from Gaza and allowed humanitarian aid and all the needs of the Gaza people to return to strip streets," Hamas media adviser Taher al-Nono, told Reuters news agency.
Criticism of Israel is increasing.
UN Secretary-General Antonio Guterres said he expressed "shocking" at Israel's offensive end in Gaza and called for an immediate ceasefire.
Germany is one of Israel's most important supporters and expresses deep concern about the offensive.
"The massive military offensive also includes the catastrophic humanitarian situation on the Gaza population and the remaining hostages will continue to deteriorate and the prospect of a long-term ceasefire is urgently needed," its federal foreign ministry said in a statement.
French Foreign Minister Jean-Noel Barrot called for aid to be restored to Gaza after the offense was confirmed.
Even before the offensive, international pressure on Israel was growing.
Seven European countries urged Israel to "reverse its current Gaza policy" on Friday.
Leaders in Iceland, Ireland, Luxembourg, Malta, Slovenia, Spain and Norway issued a joint statement about what they called "humanitarian humanitarian disaster that is happening before us in Gaza".
Tom Fletcher, the head of humanitarianism in the United Nations, called for decisive action to prevent genocide in Gaza.
He criticized the Israeli joint program to replace Gaza's international aid mechanism as a "waste of time." He said more than 160,000 pallets of aid had been "prepared to move" at the border but was blocked by Israel.
Volker Turk, the head of human rights at the United Nations, said on Friday that Israel's bombing campaign aims to achieve "permanent demographic change in Gaza" and is in "violation of international law."
