Six prisoners were killed in Gaza, prompting protests from Israelis and a strike request from labor unions.

Amid calls for a general strike by Israel's largest labor union, angry demonstrators are staging a large-scale protest demanding a ceasefire.

Israel's major labor union called for a strike after the bodies of six more captives were found in Gaza.

On Sunday night, the largest anti-government demonstration in Israel since the start of the Gaza war took place, leading to clashes between demonstrators and security forces.

Demonstrators chanted 'Now! Now!' demanding Israeli Prime Minister Netanyahu to cease fire with the Palestinian group Hamas and return the remaining captives.

Many Israelis blocked roads in Tel Aviv and demonstrated in front of Prime Minister Netanyahu's office in West Jerusalem.

The 'Hostages and Missing Families Forum,' representing families of hostages in Gaza, stated that the deaths of six hostages were a direct result of Prime Minister Netanyahu's failure to secure an agreement to stop the fighting and return their loved ones.

'They all survived abuse, torture, and starvation as hostages of Hamas for about 11 months, only to be killed in the past few days,' the forum stated.

Gil Dickman, a cousin of Carmel Gat whose body was returned, urged the Israeli public to put more pressure on the government. 'Come out to the streets, blockade the country until everyone is back. They can still be saved,' Dickman posted on X.

Gideon Levi, a columnist for Israel's 'Haaretz' newspaper, told Al Jazeera that Prime Minister Netanyahu is defending right-wing parties within the government who oppose concessions to Hamas.

"They (political parties) don't care about hostages or anything."

Levy stressed that within the largest power in the government, Prime Minister Netanyahu's Likud party, Prime Minister Netanyahu holds significant power and the party supports him.

"Therefore, challenges from within the government are very limited," he said. "The real and only challenge would be on the streets, but it's too early to determine."

On the other hand, for the first time since October 7, Israel's largest labor union federation, Histadrut, has called for a general strike to pressure the government to sign a ceasefire agreement.

The union announced its plan to close Ben Gurion Airport, Israel's major air transportation hub, on Monday at 8:00 a.m. (5:00 a.m. Japan time) to shut down or disrupt major sectors of the Israeli economy, including banking and healthcare.

"Trade is more important than anything else. We're holding body bags instead of trade.

He said he has the support of Israel's major manufacturers and entrepreneurs in the high-tech sector. The alliance of the most influential voices in the Israeli economy reflected the magnitude of the nation's anger over the deaths of the six captives.

Some of the municipal services in the economic center of Tel Aviv, Israel, will be closed on Monday.

The Israeli Manufacturers' Association supports the strike and condemned the government for not fulfilling its "moral obligation" to bring back the prisoners.

The association's representative, Ron Tomer, stated, "Without the return of the hostages, it would not be possible to end the war or to rebuild both the society and the Israeli economy."

Yair Lapid, the opposition leader and former prime minister of Israel, expressed his support for the strike.

However, Finance Minister Bezalel Smotrich requested the Attorney General Gali Baharav-Miara to urgently petition the court to prevent the planned nationwide strike.

In a letter, Smotrich claimed that the strike is aimed at unduly influencing important political decisions of politicians on issues related to national security, and that it lacks legal basis.

He also stated that a widespread strike, including the closure of domestic flights, would cause significant economic damage during wartime.

Negotiations for a ceasefire between Israel and Hamas have been drawn out for several months, with many criticizing Prime Minister Netanyahu for not reaching an agreement.

Since October 7th, the Israeli military has killed at least 40,738 people and injured 94,154 people in the war against Gaza. In the Hamas-led attack on October 7th, an estimated 1,139 people were killed in Israel and about 250 people were detained by Hamas.
