Israeli forces battled Hamas fighters and pounded targets in the Gaza Strip on Sunday as Prime Minister Benjamin Netanyahu warned of a "long and difficult" war ahead sparked by the Palestinian militant group's massive surprise attack.
The Israeli army said tens of thousands of soldiers were deployed to fight militants in southern desert regions near the coastal enclave, to rescue Israeli hostages and then evacuate the entire region within 24 hours.
"We'll reach each and every community till we kill every terrorist in Israel," vowed military spokesman Daniel Hagari, a day after hundreds of Hamas fighters crossed into Israel using vehicles, boats and even motorised paragliders.
"Our mission for the upcoming 24 hours is to evacuate all residents" from communities around the Gaza Strip, he told journalists amid the fighting that has left hundreds dead on both sides.

Israel also came under attack from the north on Sunday when Lebanon's Hezbollah movement launched missiles and artillery shells "in solidarity" with the unprecedented Hamas offensive.
Israel was shocked when Gaza's rulers Hamas launched a multi-pronged assault at dawn on Saturday with thousands of rockets and ground, air and sea forces, attacking and infiltrating Israeli towns and kibbutz communities.
The worst fighting in decades has killed more than 200 Israelis and wounded over 1,000, leaving bodies of civilians strewn on roads, while on the Gaza side at least 313 have died and over 1,700 were reported wounded.
What is the cause of the conflict?
It comes against a backdrop of surging violence between Israel and Palestinian militants in the Israeli-occupied West Bank, where a Palestinian authority exercises limited self-rule, opposed by Hamas that wants Israel destroyed.
The attack was launched the day after the 50th anniversary of the outbreak of the Yom Kippur War, when the Israeli army was surprised by Syrian and Egyptian tank columns.
The Jewish state considers Hamas, which advocates the destruction of Israel, as its sworn enemy. But since the ten-day war between the two camps in 2021, and the significant damage inflicted on the Gaza Strip, relative stability has been maintained in the Palestinian territory, controlled by the Islamist group since 2007, while violence has been shaking the West Bank for eighteen months.
Only sporadic clashes were reported on the border between the territory and Israel, claimed by Islamic Jihad - but Hamas generally kept away. To ensure a certain economic peace, Israel had distributed thousands of work permits to residents of the enclave, while maintaining a strict blockade of the territory.

Why is Hamas doing it now?
The United States has been seeking a deal to normalise ties between Israel and Saudi Arabia, seen by Israelis as the biggest prize yet in their decades-long quest for Arab recognition. Palestinians fear any such agreement could sell out their dreams of an independent state.
Osama Hamdan, the leader of Hamas in Lebanon, told Reuters that Saturday's operation should make Arab states realize that accepting Israeli security demands would not bring peace.
Across the Middle East, there were demonstrations in support of Hamas, with Israeli and U.S. flags set on fire and marchers waving Palestinian flags in Iraq, Lebanon, Syria and Yemen. Iran and Hezbollah, Iran's Lebanese allies, praised the Hamas attack.
Hamas said the attack was driven by what it called escalated Israeli attacks on Palestinians in the West Bank and Jerusalem and against Palestinians in Israeli prisons.
The conflict could undermine U.S.-backed efforts to broker a normalisation of relations between Israel and Saudi Arabia - a regional security realignment that could threaten Palestinian aspirations for statehood and the ambitions of Hamas's main backer, Iran.
Joost Hiltermann, Middle East director of the International Crisis Group, said Hamas may have acted in part due to fear of a "looming further marginalization of the Palestinian cause in Palestinian eyes" if Saudi Arabia recognizes Israel.
With Israel expected to respond forcefully to Saturday's attacks, Arab states will likely feel obliged to take a harder stance in line with public sentiment, he said. "If that all happens, then I would foresee a scenario where, just like we have a cold peace between Israel and Jordan, between Israel and Egypt, we end up with a cooling of the relationship between Israel and the Emirates and probably a delay, at least, of any sort of deal between Israel and Saudi Arabia," he said.

How did it start?
At about 6.30 a.m. (0430 GMT) Palestinian Islamist group Hamas fired a huge barrage of rockets across southern Israel, with sirens heard as far away as Tel Aviv and Beersheba.
Hamas said it had fired 5,000 rockets in a first barrage. Israel's military said 2,500 rockets were fired.
Smoke billowed over residential Israeli areas and people sheltered behind buildings as sirens sounded overhead. At least one woman was reported killed by the rockets.
The barrage served as cover for an unprecedented multi-pronged infiltration of fighters, with the Israeli military saying at 7.40 a.m. (0540 GMT) that Palestinian gunmen had crossed into Israel.
Most fighters crossed through breaches in land security barriers separating Gaza and Israel. But at least one was filmed crossing on a powered parachute while a motorboat was filmed heading to Zikim, an Israeli coastal town and military base.
Gunmen killed at least 250 Israelis in clashes throughout Saturday and into Sunday, and escaped back into Gaza with dozens of hostages. More than 300 Gazans were killed when Israel responded with one of its most devastating days of retaliatory strikes.

Israel caught unaware
Just weeks ago Prime Minister Benjamin Netanyahu brushed aside the Palestinian issue during a speech at the United Nations and said normalization in 2020 with three other Arab nations in the so-called Abraham Accords had "heralded a new age of peace."
And the offensive carried out by Hamas on Saturday in Israeli territory fuels questions about the role of the Jewish state's intelligence and defense forces, completely taken by surprise by the commandos of the Palestinian Islamist group.
"It's very similar to what happened back then," said retired Gen. Giora Eiland, former head of the National Security Council, referring to the 1973 Yom Kippur war, "As we saw, Israel was completely surprised by a very well-coordinated attack."
An army spokesman said discussions on the effectiveness of intelligence services would take place in due course but for now the priority was on fighting. "We will talk about it when we need to talk about it," he told reporters.
Hundreds of armed Hamas men entered Israeli territory by crossing security barriers before attacking border towns. "It's an intelligence failure. You can't call it anything else," said Jonathan Panikoff, former head of US services in the Middle East. "It is a failure of the security apparatus, which calls into question what was thought to be a successful proactive approach by Israel towards Gaza."
But when the time came, Israel's security apparatus appeared to break down as a force of Hamas gunmen estimated in the hundreds by the military broke through security fences and scattered into towns. For Israelis, images of dead bodies lying in the streets or groups of civilians being driven or marched into captivity in Gaza came as a profound shock.

What is Israel's response?
Israeli air strikes battered Gaza overnight, killing more than 300 Palestinians and smashing buildings, tunnels and the houses of Hamas officials, as Prime Minister Benjamin Netanyahu vowed "mighty vengeance for this wicked day."
An Israeli military spokesperson said operations were going on in eight areas around Gaza on Sunday, while Al Hadath TV cited the Palestinian Red Crescent as saying 18 people had been killed in Israeli targeting of two homes in Gaza's Beit Hanoun district.
Palestinian health officials said 20 children were among at least 313 civilians killed. Nearly 2,000 people were wounded, they said. In southern Israel, Hamas gunmen were still fighting Israeli security forces in several places 24 hours after their incursion in the early hours of Saturday, both sides said, as more rockets were fired from Gaza, sparking air raid sirens.
"We're going to be attacking Hamas severely and this is going to be a long, long haul," a military spokesman told a briefing with reporters. Jets resumed strikes on Gaza in the morning and troops were conducting clearing operations around the blockaded enclave, including at a military base in the area of Zikim that was overrun on Saturday.
Hostage impact
Israeli troops have been battling "hundreds" of Palestinian militants at 22 locations inside Israel after they infiltrated from Gaza, the army said.
"There are still 22 locations where we are engaging with terrorists that came into Israel from the sea, from the land and from the air," army spokesman Richard Hecht told journalists, adding the Hamas attack included a "robust ground invasion."
Asked by journalists how many militants had entered Israel, Hecht said "hundreds" had "invaded" the country, adding that "hundreds" were still fighting troops inside Israel. He said there was a "severe hostage situation in Beeri and also in Ofakim", two Israeli communities in the Negev Desert, the latter 20 kilometres (more than 12 miles) from the Gaza border.
Israeli hostages have also been taken back to Gaza by the Hamas groups following their raid on Saturday.
Escalation
In the north, Hezbollah said in a statement it had carried out a rocket and artillery attack on three posts including a "radar site" in the Shebaa Farms, a slice of land occupied by Israel since 1967 that Lebanon claims. Israel responded with artillery fire on southern Lebanon. There were no reports of casualties.
"We recommend Hezbollah not to come into this and I don't think they will," Israel's army spokesperson said. Hamas leader Ismail Haniyeh said the assault that began in Gaza would spread to the West Bank and Jerusalem. Gazans have lived under an Israeli blockade for 16 years.
In a speech, Haniyeh highlighted threats to Jerusalem's Al-Aqsa Mosque, the continuation of an Israeli the blockade on Gaza and Israeli normalization with countries in the region. He said: "How many times have we warned you that the Palestinian people have been living in refugee camps for 75 years, and you refuse to recognise the rights of our people?"
Netanyahu's office said his security cabinet had approved steps to destroy the military and governmental capabilities of Hamas and Islamic Jihad, another militant group, "for many years," including cutting electricity, fuel supplies and the entry of goods into Gaza.
In Gaza, black smoke, orange flashes and sparks lit the sky from explosions. Israeli drones could be heard overhead. U.S. Secretary of State Antony Blinken spoke on Saturday with Egypt, a key intermediary between Israel and Hamas, to seek an immediate end to the offensive by the militants, the State Department said.
In a telephone call with Foreign Minister Sameh Shoukry, Blinken raised "the urgency in achieving an immediate halt to the appalling assault by Hamas terrorists against Israel," State Department spokesman Matthew Miller said.

International response
Western countries, led by the United States, denounced the attack. At the White House, President Joe Biden went on national television to say Israel had the right to defend itself, issuing a blunt warning to Iran and other countries: "This is not a moment for any party hostile to Israel to exploit these attacks to seek advantage. The world is watching," he said.
The Chinese foreign ministry urged relevant parties "to remain calm, exercise restraint and immediately end the hostilities to protect civilians and avoid further deterioration of the situation." The foreign ministry said: "The fundamental way out of the conflict lies in implementing the two-state solution and establishing an independent State of Palestine."
Egyptian President Abdel Fattah al-Sisi warned Saturday of a "vicious cycle" of violence after Hamas launched a deadly attack on Israel, which responded with devastating air strikes on Gaza.
Sisi received a call from French President Emmanuel Macron, Egypt's presidency said, and the two discussed "coordinating efforts to stop the escalation in the Gaza Strip between the Palestinian and Israeli sides."
Saudi Arabia's foreign ministry called for an "immediate cessation of violence." While adviser to Iran's Supreme Leader Ali Khamenei on Saturday congratulated Palestinian fighters, the semi-official ISNA news site reported. "We will stand by the Palestinian fighters until the liberation of Palestine and Jerusalem," it quoted Yahya Rahim Safavi as saying.
EU Foreign Policy Chief Josep Borrell said: "Using civilians as hostages is a blatant violation of all laws. I will do my utmost to contribute to their freedom." He added he was travelling to Muscat, Oman to meet Arab counterparts. "Even at this tragic moment, we recall the importance of working towards a lasting and sustainable peace through reinvigorated efforts in the Middle East Peace Process," he said.
