JERUSALEM • Tens of thousands of Israelis poured into the streets of cities across the country on Sunday night in a spontaneous outburst of anger after Prime Minister Benjamin Netanyahu abruptly fired his defense minister for challenging the Israeli leader’s judicial overhaul plan.

Protesters in Tel Aviv blocked a main highway and lit large bonfires, while police scuffled with protesters who gathered outside Netanyahu’s private home in Jerusalem.

The unrest deepened a monthslong crisis over Netanyahu’s plan to overhaul the judiciary, which has sparked mass protests, alarmed business leaders and former security chiefs and drawn concern from the United States and other close allies.

Netanyahu’s dismissal of Defense Minister Yoav Gallant signaled that the prime minister and his allies will barrel ahead this week with the overhaul plan. Gallant had been the first senior member of the ruling Likud party to speak out against it, saying the deep divisions were threatening to weaken the military.

But as droves of protesters flooded the streets late into the night, Likud ministers began indicating willingness to hit the brakes. Culture Minister Micky Zohar, a Netanyahu confidant, said the party would support him if he decided to pause the judicial overhaul.

In a brief statement, Netanyahu’s office said late Sunday the prime minister had dismissed Gallant. Netanyahu later tweeted “we must all stand strong against refusal.”

Tens of thousands of Israelis poured into the streets in protest after Netanyahu’s announcement, blocking Tel Aviv’s main artery, transforming the Ayalon highway into a sea of blue-andwhite Israeli flags and lighting a large bonfire in the middle of the road.

Demonstrations took place in Beersheba, Haifa and Jerusalem, where thousands of people gathered outside Netanyahu’s private residence. Police scuffled with protesters and sprayed the crowd with a water cannon.

Inon Aizik, 27, said he came to demonstrate outside Netanyahu’s private residence in central Jerusalem because “bad things are happening in this country,” referring to the judicial overhaul as “a quick legislative blitz.”

Netanyahu’s decision came less than a day after Gallant, a former senior general, called for a pause in the controversial legislation until after next month’s Independence Day holidays, citing the turmoil in the ranks of the military.

Gallant had voiced concerns that the divisions in society were hurting morale in the military and emboldening Israel’s enemies. “I see how the source of our strength is being eroded,” Gallant said.

While several other Likud members had indicated they might follow Gallant, the party quickly closed ranks on Sunday, clearing the way for his dismissal.

Galit Distal Atbaryan, Netanyahu’s public diplomacy minister, said that Netanyahu summoned Gallant to his office and told him “that he doesn’t have any faith in him anymore and therefore he is fired.”
