As a truce ended between Israel and Hamas on Friday, both sides traded blame for reigniting the war.

Israel accused Hamas of violating the cease-fire by firing rockets toward Israeli territory just after 7 a.m. local time, as negotiations failed to further extend the truce. The Israeli military has since resumed combat in the Hamas-ruled Gaza Strip, with ground, air and naval forces striking more than 200 "terror targets" in the north and south thus far, according to the Israel Defense Forces.

Meanwhile, Hamas accused Israel of "persistently rejecting" all its offers to release more hostages in Gaza amid negotiations to extend the cease-fire agreement on Thursday night. Hamas alleged that it had offered to hand over more Israeli detainees, including the elderly, as well as the bodies of those who have died in captivity, which the militant group claimed was a result of previous Israeli bombings.

"However, the [Israeli] occupation, driven by a predetermined decision to resume criminal aggression, remained unresponsive," Hamas said in a statement.

An Israeli kibbutz confirmed Friday the death of three of its residents who were taken hostage by Hamas during the Oct. 7 attack.

Kibbutz Nir Oz announced that 85-year-old resident Aryeh Zalmanovich has died in Hamas captivity in the Gaza Strip. Zalmanovich was one of the founders of the kibbutz, which is located in southern Israel near the border with Gaza.

“Father of two sons and grandfather of five grandchildren. Aryeh was a man of the land all his life who was engaged in agriculture and field crops,” the kibbutz said in a statement. “A man of books and has a wide knowledge of history and knowledge of the country.”

Gaza's militant rulers, Hamas, released a video in mid-November that appeared to show Zalmanovich looking ill. The group claimed he had later died.

Kibbutz Nir Oz also announced that 54-year-old resident Ronen Engel has died in Hamas captivity in Gaza. The kibbutz described Engel as a "photographer, MDA volunteer and motorcycle enthusiast." His wife and two daughters were also kidnapped to Gaza on Oct. 7 and released this week, according to the kibbutz.

A third resident of kibbutz Nir Oz, 56-year-old resident Maya Goren, was also confirmed to have died in Hamas captivity in Gaza. Her husband was among those killed on Oct. 7, according to the kibbutz.

"Maya was a hardworking and dedicated kindergarten teacher, and gave loving care to the kibbutz children for many years," the kibbutz said in a statement.

Israel will no longer hold fire as negotiations with Hamas progress, an Israeli security source told ABC News on Friday.

The source said Israeli forces will only cease-fire for 24 hours if Hamas sends a list of at least 10 hostages to be released, the list is approved by Israel and everyone on that list is safely returned home.

United Nations High Commissioner for Human Rights Volker Turk warned Friday that the resumption of hostilities between Israel and Hamas in the Gaza Strip is "catastrophic," with the situation now "beyond crisis point."

"I urge all parties and states with influence over them to redouble efforts, immediately, to ensure a ceasefire -- on humanitarian and human rights grounds," Turk said in a statement.

Hundreds of demonstrators gathered on Saturday at the first anti-government protest held in Tel Aviv since Oct. 7.

"We don't want a radical government. We didn't want it before, and we don't want it now," Moshe Radman, who helped organize the protest, told ABC News. "We are telling them we want a new government as soon as possible."

Radman says people were scared to protest in the early days of the war -- but that things have changed in the last few weeks. He predicts the demonstrations will grow.

"We gave them 57 days, and week after week we saw that they are not doing the right thing. And I think we understand that we are headed towards a long war, so we have to do it now," he said.

Protesters Sharon and Eyal Eshel said their 19-year-old daughter Roni, an Israel Defense Forces soldier, was killed in the Oct. 7 attack by Hamas militants while stationed at the Nahal Oz kibbutz. Her family said they have yet to receive a single phone call from Israeli Prime Minister Benjamin Netanyahu.

"We are looking for answers, we want answers from the IDF, we want answers from the government. And we want the man who is in charge, we need him to take responsibility," Sharon Eshel told ABC News.

"It's not the time to say, 'It's not the time,'" Eyal Eshel told ABC News, calling on Netanyahu to sit down with him and answer his questions. "Enough is enough."

In response to criticism and pool polling numbers, Netanyahu has previously said he has no plans of stepping down.
