TEL AVIV, ISRAEL -- Tens of thousands of grieving and angry Israelis surged into the streets Sunday night after six more hostages were found dead in Gaza, chanting 鈥淣ow! Now!鈥 as they demanded that Israeli Prime Minister Benjamin Netanyahu reach a ceasefire with Hamas to bring the remaining captives home.

The mass outpouring appeared to be the largest such demonstration in 11 months of war and protesters said it felt like a possible turning point, although the country is deeply divided.

Israel鈥檚 largest trade union, the Histadrut, further pressured the government by calling a general strike for Monday, the first since the Oct. 7 Hamas attack that started the war. It aims to shut down or disrupt major sectors of the economy, including banking, health care and the country鈥檚 main airport.

Ceasefire negotiations have dragged on for months. Many blame Netanyahu for failing to reach a deal, which opinion polls show a majority of Israelis favor. But the prime minister also has significant support for his strategy of 鈥渢otal victory鈥 against Hamas, even if a deal for the hostages has to wait.

Thousands of people, some of them weeping, gathered Sunday night outside Netanyahu's office in Jerusalem. In Tel Aviv, hostages' relatives marched with coffins to symbolize the toll.

鈥淲e really think that the government is making these decisions for its own conservation and not for the lives of the hostages, and we need to tell them, 鈥楽top!鈥欌 said Shlomit Hacohen, a Tel Aviv resident.

Three of the six hostages found dead 鈥 including an Israeli-American 鈥 were reportedly scheduled to be released in the first phase of a ceasefire proposal discussed in July, and this only added to the sense of fury and frustration among the protesters.

鈥淣othing is worse than knowing that they could have been saved,鈥 said Dana Loutaly. 鈥淪ometimes it takes something so awful to shake people up and get them out into the streets.鈥

Gaza hostages 6 bodies recovered

The military said all six hostages were killed shortly before Israeli forces arrived. 鈥淲hoever murders hostages doesn鈥檛 want a deal,鈥 Netanyahu said, blaming the Hamas militant group for the stalled negotiations.

One hostage was Israeli-American Hersh Goldberg-Polin, 23, a native of Berkeley, California, who lost part of his left arm to a grenade in the attack. In April, a Hamas-issued video showed him alive, sparking new protests in Israel.

The army identified the others as Ori Danino, 25; Eden Yerushalmi, 24; Almog Sarusi, 27; Alexander Lobanov, 33; and Carmel Gat, 40.

The Israeli Health Ministry said autopsies had determined the hostages were shot at close range and died on Thursday or Friday. The army said the bodies were recovered from a tunnel in the southern Gaza city of Rafah, around a kilometer (half a mile) from where another hostage was rescued alive last week.

Lt. Col. Nadav Shoshani, a military spokesperson, said Israeli forces found the bodies several dozen meters (yards) underground as 鈥渙ngoing combat鈥 was underway, but that there was no firefight in the tunnel itself. He said there was no doubt Hamas had killed them.

Hamas has offered to release the hostages in return for an end to the war, the withdrawal of Israeli forces from Gaza and the release of a large number of Palestinian prisoners, including high-profile militants.

Izzat al-Rishq, a senior Hamas official, said the hostages would still be alive if Israel had accepted a U.S.-backed ceasefire proposal that Hamas said it had agreed to in July.

Funerals began, with more outrage. Sarusi's body was wrapped in an Israeli flag. 鈥淵ou were abandoned on and on, daily, hour after hour, 331 days,鈥 his mother, Nira, said. 鈥淵ou and so many beautiful and pure souls. Enough. No more.鈥

Divisions in Israel, and in the government

Netanyahu has vowed to continue the fighting until Hamas is destroyed.

Top security officials say the intense pressure on Hamas has created favorable conditions for a ceasefire deal. The army, noting the difficulty of rescue operations, has acknowledged that a deal is the only way to bring home large numbers of hostages safely.

Israel hostage protest

But critics have accused the prime minister of putting his personal interests over those of the hostages. The war's end likely will lead to an investigation into his government鈥檚 failures in the Oct. 7 attacks, the government's collapse and early elections.

Some analysts said the public outcry over the six hostages who died could signal a new level of political pressure on Netanyahu.

鈥淚 think this is an earthquake. This isn鈥檛 just one more step in the war,鈥 said Nomi Bar-Yaacov, associate fellow in the International Security Program at Chatham House, shortly before Sunday's protests.

Divisions also have been exposed within the government. Senior military and security officials, including Defense Minister Yoav Gallant, have warned that time is running out.

Israel's Channel 12 reported that Netanyahu got into a shouting match at a security Cabinet meeting Thursday with Gallant, who accused him of prioritizing control of a strategic corridor along the Gaza-Egypt border 鈥 a major sticking point in the talks 鈥 over the lives of the hostages.

An Israeli official confirmed the report and said three of the hostages 鈥 Goldberg-Polin, Yerushalmi and Gat 鈥 had been slated to be released in the first phase of a ceasefire proposal discussed in July. The official was not authorized to brief media about the negotiations and spoke on condition of anonymity.

鈥淚n the name of the state of Israel, I hold their families close to my heart and ask forgiveness,鈥 Gallant said Sunday. The Cabinet was meeting Sunday night.

A forum of hostage families has demanded a 鈥渃omplete halt of the country鈥 to push for a ceasefire and hostage release.

Even a mass outpouring of anger would not immediately threaten Netanyahu or his far right government. He still controls a majority in parliament. But he has caved in to public pressure before. A general strike last year helped lead to a delay in his controversial judicial overhaul.

A family's high-profile campaign

Goldberg-Polin鈥檚 parents, U.S.-born immigrants to Israel, became perhaps the most high-profile relatives of hostages on the international stage. They met with U.S. President Joe Biden and Pope Francis and on Aug. 21, they addressed the Democratic National Convention 鈥 after sustained applause and chants of 鈥渂ring him home.鈥

Biden on Sunday said he was 鈥渄evastated and outraged.鈥 The White House said he spoke with Goldberg-Polin鈥檚 parents and offered condolences.

Some 250 hostages were taken on Oct. 7. Israel now believes 101 remain in captivity, including 35 who are thought to be dead. More than 100 were freed during a ceasefire in November in exchange for the release of Palestinians imprisoned by Israel. Eight have been rescued by Israeli forces. Israeli troops mistakenly killed three Israelis who escaped captivity in December.

Hamas-led militants killed some 1,200 people, mostly civilians, when they stormed into southern Israel on Oct. 7. Israel's retaliatory offensive in Gaza has killed over 40,000 Palestinians, according to local health officials, who do not say how many were militants.

On Sunday, an Israeli strike hit a car on a road in southern Gaza and killed four Palestinians, according to Aqsa Martyrs Hospital officials and an AP journalist who counted the bodies.

The war has displaced the vast majority of Gaza's 2.3 million people, often multiple times, and plunged the besieged territory into a humanitarian catastrophe.
