Israel battles Hamas for a second day after mass incursion and trades fire with Lebanon’s Hezbollah

TEL AVIV, Israel — Israeli soldiers battled Hamas fighters in the streets of southern Israel on Sunday and launched retaliation strikes that leveled buildings in Gaza, while in northern Israel a brief exchange of strikes with Lebanon’s Hezbollah militant group raised fears of a broader conflict.

There was still some fighting underway more than 24 hours after an unprecedented surprise attack from Gaza, in which Hamas fighters, backed by a volley of thousands of rockets, broke through Israel’s security barrier and rampaged through nearby communities. The fighters took captives back into the coastal Gaza enclave, including women, children and the elderly, who they will likely try to trade for thousands of Palestinian prisoners held by Israel.

Israeli Prime Minister Benjamin Netanyahu said the country was at war and would exact a heavy price from its enemies. Hamas leaders said they were prepared for further escalation.

Israeli media, citing rescue service officials, said at least 300 people were killed, including 26 soldiers, while in Gaza officials said 313 people had died. An Israeli military official said hundreds of militants had been killed and dozens captured.

Civilians paid a staggering cost for the violence on both sides. Israeli TV news aired a stream of accounts from the relatives of captive or missing Israelis, who wailed and begged for assistance amid a fog of uncertainty surrounding the fate of their loved ones. In Gaza, residents fled homes near the border to escape Israeli strikes, fleeing deeper inside the territory after warnings in Arabic from the Israeli military.

In neighboring Egypt, a policeman shot dead two Israeli tourists and an Egyptian at a tourist site in Alexandria, the Interior Ministry said. Egypt made peace with Israel decades ago, but anti-Israel sentiment runs high in the country, especially during bouts of Israeli-Palestinian violence.

Previous conflicts between Israel and Gaza’s Hamas rulers brought widespread destruction in Gaza and days of rocket fire on Israeli towns. The situation is potentially more volatile now, with Israel’s far-right government stung by the unprecedented security breach and Palestinians in despair over a never-ending occupation in the West Bank and suffocating blockade of Gaza.

The flare-up on Israel’s northern border also threatened to draw into the battle Hezbollah, a fierce enemy of Israel’s which is backed by Iran and estimated to have tens of thousands of rockets at its disposal. Hezbollah fired dozens of rockets and shells on Sunday at three Israeli positions in a disputed area along the border and Israel’s military fired back using armed drones.

Rear Adm. Daniel Hagari, an Israeli military official, told reporters the situation at the northern border was calm after the exchange. But he said fighting was still underway in the south and that there were still hostage situations there.

He said troops had moved into every community near the Gaza frontier, where they planned to evacuate all civilians and scour the area for any remaining militants. Hagari said the military had killed 400 militants since the start of the war and captured dozens more.

“We will go through every community until we kill every terrorist that is in Israeli territory,” he said. In Gaza, “every terrorist located in a house, all the commanders in houses, will be hit by Israeli fire. That will continue escalating in the coming hours.”

Hamas said that overnight it had continued to send forces and equipment into “a number of locations inside our occupied territories,” referring to Israel.

The surprise attack Saturday was the deadliest on Israel in decades. In an assault of startling breadth, Hamas gunmen used explosives to break through the border fence enclosing Gaza, then crossed with motorcycles, pickup trucks, paragliders and speed boats on the coast. They rolled into as many as 22 locations outside the Gaza Strip early Saturday morning, including towns and other communities as far as 15 miles (24 kilometers) from the Gaza border, while Hamas launched thousands of rockets at Israeli cities.

“Israel is waking up this morning to a terrible morning,” said Lt. Col. Richard Hecht, an Israeli military spokesman. “There are a lot of people killed... children, grandmothers, families, bodies.”

Israeli media said at least 300 people were killed and 1,500 wounded in Saturday’s attack. Hamas fighters took an unknown number of civilians and soldiers captive into Gaza, and a line of Israelis with missing relatives snaked outside a police station in central Israel to supply investigators with DNA samples and other means that could help identify their family members.

Israel struck 426 targets in Gaza, its military said, flattening residential buildings in giant explosions. That included a 14-story tower that held dozens of apartments as well as Hamas offices in central Gaza City. Israeli forces fired a warning just before.

Among the 313 killed in Gaza were 20 children, and close to 2,000 wounded, the Palestinian Health Ministry said. UNRWA, the United Nations agency for Palestinians, said more than 20,000 Palestinians left Gaza’s border region to head further inside the territory and take refuge in U.N. schools.

In a televised address Saturday night, Israeli Prime Minister Benjamin Netanyahu said the military will use all of its strength to destroy Hamas’ capabilities. “All the places that Hamas hides in, operates from, we will turn them into ruins,” he added.

“Get out of there now,” he told Gaza residents, who have no way to leave the tiny, overcrowded Mediterranean territory. Gaza’s 2.3 million people have endured a border blockade, enforced to varying degrees by Israel and Egypt, since Hamas militants seized control in 2007.

A major question now was whether Israel will launch a ground assault into Gaza, a move that in the past has brought intensified casualties. Netanyahu vowed that Hamas “will pay an unprecedented price.” But, he warned, “This war will take time. It will be difficult.”

Israel’s military says it is bringing four divisions of troops as well as tanks to the Gaza border, joining 31 battalions already in the area.

Hamas said it had planned for a long fight. “We are prepared for all options, including all-out war,” the deputy head of the Hamas political bureau, Saleh al-Arouri, told Al-Jazeera TV. “We are ready to do whatever is necessary for the dignity and freedom of our people.”

The abduction of Israeli civilians and soldiers also raised a particularly thorny issue for Israel, which has a history of making heavily lopsided exchanges to bring captive Israelis home. Israel is holding thousands of Palestinians in its prisons. The military has confirmed that a “substantial” number of Israelis were abducted Saturday without giving an exact figure.

An Egyptian official said Israel has sought help from Cairo to ensure the safety of the hostages, and that Egypt’s intelligence chief had contacted Hamas and the smaller but more radical Islamic Jihad group, which also took part in the incursion, to seek information. Egypt has often mediated between the two sides in the past.

The official said Palestinian leaders claimed that they don’t yet have a “full picture” of hostages, but said those who were brought into Gaza were taken to “secure locations” across the territory.

“It’s clear that they have a big number — several dozens,” said the official, who asked not to be identified because he was not authorized to brief media.

Egypt also spoke with both sides about a potential cease-fire, but the official said Israel was not open to a truce “at this stage.”

The shadowy leader of Hamas’ military wing, Mohammed Deif, said the assault was in response to the 16-year blockade of Gaza, and a series of recent incidents that have brought Israeli-Palestinian tensions to a fever pitch.

Deif, who does not appear in public, said in a recorded message that the attack was only the start of what he called “Operation Al-Aqsa Storm,” and called on Palestinians from east Jerusalem to northern Israel to join the fight.

In Gaza, much of the population was thrown into darkness Saturday night as Israel cut off electricity. Netanyahu’s office said in a statement that Israel would stop supplying electricity, fuel and goods to Gaza.

Before daybreak Sunday, militants fired more rockets from Gaza, hitting a hospital in the Israeli coastal town of Ashkelon. The military said patients had been evacuated before the strike.

School was canceled across Israel.

U.S. President Joe Biden said from the White House that he had spoken with Netanyahu to say the United States “stands with the people of Israel in the face of these terrorist assaults. Israel has the right to defend itself and its people, full stop.”

The Hamas incursion on Simchat Torah, a Jewish holiday, revived painful memories of the 1973 Mideast war, in which Egypt and Syria launched a surprise attack on Yom Kippur, the holiest day of the Jewish calendar, aiming to take back Israeli-occupied territories. The comparison sharpened criticism of Netanyahu and his far-right allies, who had campaigned as security hawks.
