Israel-Gaza live updates: Protest erupts in Tel Aviv over cease-fire, hostage deal

The Israel Police has condemned what it called "brutal vandalism" during a night of anti-government demonstrations in Tel Aviv, sparked by the deaths in captivity of six of Hamas' Gaza hostages.

In a statement, the Police Spokesperson's Unit said officers arrested 29 suspects for a range of offenses including disorderly conduct, assaulting officers and vandalism.

The violence followed a planned protest at the Kaplan Junction in Tel Aviv, the statement said, after which "hundreds of protesters" left the approved demonstration area and moved to the Ayalon Highway, "with the intent to disrupt traffic and public order."

Some marchers "violently pushed against barricades and officers, leading to a confrontation during which a policewoman was injured and lost consciousness," the statement said. The officer was evacuated for medical treatment.

As officers attempted to clear the area, some protesters "breached security perimeters, blocked the Ayalon Highway, and set fires, while firing fireworks that nearly hit officers," police said.

"The Israel Police strongly condemns the acts of vandalism and violence directed at officers," the statement read. "We will pursue legal action against those responsible to the fullest extent of the law."

The protesters were demanding that Prime Minister Benjamin Netanyahu and his government agree to a cease-fire and hostage-release deal with Hamas.

A general strike called by Israel's largest trade union -- Histadrut -- began on Monday morning in a bid to pressure the government into reaching an accord with the militant group.

Vice President Kamala Harris and second gentleman Doug Emhoff spoke with the parents of Hersh Goldberg-Polin, an American-Israeli hostage who was found dead in Gaza on Saturday along with five other Oct. 7 hostages, according to the Israel Defense Forces.

The vice president and her husband called parents Rachel Goldberg and Jon Polin on Sunday to "express our condolences following the brutal murder of their son by Hamas terrorists," Harris said in a statement on X.

"My heart breaks for their pain and anguish," Harris continued.

"I told them: As they mourn this terrible loss, they are not alone. Our nation mourns with them," Harris said.

Protesters took to the streets of Tel Aviv Sunday night, demanding a cease-fire agreement and the release of the remaining hostages being held by Hamas terrorists.

The demonstration came a day after Israel Defense Forces recovered the bodies of six hostages in tunnels under the city of Rafah in the Gaza Strip.

Protesters were seen waving Israeli flags as they demanded a cease-fire agreement, chanting "Deal. Now."

At least six people were killed on Sunday when Israel Defense Forces conducted an airstrike on a school in Gaza City, according to Gaza Civil Defense.

The IDF said in a statement that the strike was aimed at Hamas terrorists they allege were operating a command-and-control center inside the Safad school to plan and carry out terrorist attacks against the IDF and Israel.

"Prior to the strike, numerous steps were taken to mitigate the risk of harming civilians, including the use of precise munitions, aerial surveillance, and additional intelligence," the IDF said in a statement.

The Gaza Civil Defense confirmed the Safad school was hit in the IDF strike, but said the school houses displaced people from the Al-Zeitoun area east of Gaza City.
