(NEW YORK) -- As the Israel-Hamas war continues, the latest round of cease-fire discussions appears to have reached an impasse.
Meanwhile, after six hostages were found dead in Gaza, protests erupted in Israel. Protesters have lashed out at Prime Minister Benjamin Netanyahu and demanded the government bring the hostages home.
Here's how the news is developing:
Biden 'outraged' by Israel's killing of American activist
President Joe Biden said he is "outraged and deeply saddened" by the killing of American citizen Aysenur Ezgi Eygi in the West Bank by Israeli forces.
"The shooting that led to her death is totally unacceptable," the president said in a statement published Wednesday morning.
The Israel Defense Forces published its initial report into the killing on Tuesday, finding it "highly likely" that the dual American-Turkish activist "was hit indirectly and unintentionally by IDF fire which was not aimed at her."
Biden said the U.S. government has "full access" to the preliminary investigation "and expects continued access as the investigation continues, so that we can have confidence in the result."
"There must be full accountability," the president said. "And Israel must do more to ensure that incidents like this never happen again."
Eygi, 26, was with the International Solidarity Movement in the West Bank, working to protect local Palestinian farmers from attacks by Israeli settlers.
Biden said Wednesday that the violence in the West Bank "has been going on for too long."
"Violent extremist Israeli settlers are uprooting Palestinians from their homes," he continued. "Palestinian terrorists are sending car bombs to kill civilians."
"I will continue to support policies that hold all extremists -- Israelis and Palestinians alike -- accountable for stoking violence and serving as obstacles to peace," he said.
Two Israeli soldiers killed in Gaza helicopter crash
Two Israeli soldiers were killed and seven injured were injured in a helicopter crash in southern Gaza on Tuesday night, the Israel Defense Forces said.
The helicopter "was on a mission to evacuate an injured soldier to a hospital for medical treatment," but "crashed while landing in the Rafah area" in the south of the territory, the IDF wrote on X.
"An initial inquiry conducted indicates that the crash was not caused by enemy fire," the force said. "The cause of the crash is still under investigation."
Seven other troops were "injured to varying degrees, the IDF said. They have been hospitalized for treatment.
Israeli Air Force commander, Maj. Gen. Tomer Bar, appointed an investigative committee to probe the incident, the IDF added.
Israel hits dozens of Hezbollah targets in Lebanon
Israeli warplanes "struck approximately 30 Hezbollah launchers and terror infrastructure sites which posed a threat to Israeli civilians" in southern Lebanon overnight, the Israel Defense Forces (IDF) said Wednesday.
The strikes occurred in the areas of Jibbain, Naqoura, Deir Seryan and Zibqin, the IDF said. Israeli artillery also hit the area of Al-Dahira.
Suspect killed after West Bank 'ramming attack,' IDF says
One person was critically injured in an alleged ramming attack near an Israeli settlement in the West Bank on Wednesday.
The Israel Defense Forces said that the "terrorist" attacker "was neutralized at the scene." The incident occurred at the Givat Asaf junction, close to the Israeli settlement of Beit El.
Magen David Adom -- Israel's emergency service -- said its responders were "treating a male about 20 years old in critical condition."
The MDA said on social media that the victim was hit by a "fuel tanker."
Death toll in Gaza surpasses 41,000: Gaza Ministry of Health
The death toll in Gaza has passed 41,000 as of Tuesday, according to the Hamas-run Gaza Ministry of Health.
The ministry reported that 41,020 people have died and 94,925 have been injured since Israel launched its war against Hamas in Gaza on Oct. 8, 2023, following the Oct. 7 terrorist attacks.
That figure does not distinguish between civilians and combatants.
IDF releases video of tunnel where 6 hostages were held
The Israel Defense Forces has released footage of the blood-stained tunnel where six hostages, including Israeli-American Hersh Goldberg-Polin, were held captive and murdered last month.
The "passageway" tunnel spanned 120 meters and was 20 meters deep, the IDF said.
The IDF estimates the hostages were in the tunnel for "weeks."
The Israeli military believes the six hostages were shot and killed on Aug. 29. The IDF said its soldiers found one of the tunnel’s shafts on Aug. 30, and the hostages’ bodies were discovered on Aug. 31.
The IDF said the hostages were killed with bullets from two guns.
The Hostages Families Forum Headquarters said in a statement that the "shocking" video "proves the unimaginable, inhuman conditions in which the 6 hostages Alex, Hersh, Eden, Ori, Carmel and Almog were held for months."
"Carmel, Hersh, Alex, Almog, Ori, and Eden suffered until their last breath. They begged to be released, pleaded for their lives," the group said. "Time is running out! That light, that hope, cannot die. A deal must be signed NOW!"
Blinken condemns 'unprovoked' Israeli killing of American activist
Secretary of State Antony Blinken said Tuesday that the IDF's initial report into the killing of U.S. citizen Aysenur Ezgi Eygi suggests "her killing was both unprovoked and unjustified."
"No one should be shot and killed for attending a protest. No one should have to put their life at risk just for freely expressing their views," Blinken said, using some of the strongest terms to condemn the killing by any American official yet.
"In our judgment, Israeli security forces need to make some fundamental changes in the way that they operate in the West Bank, including changes to their rules of engagement," Blinken continued, adding that the U.S. was well aware of longstanding allegations concerning Israeli authorities' use of excessive force against Palestinians in the West Bank.
"Now we have the second American citizen killed at the hands of Israeli security forces. It's not acceptable. It has to change, and we'll be making that clear to the senior-most members of the Israeli government," Blinken said.
"Now we're looking carefully at the results of this investigation, but even on an initial read and even accepting it at face value, it's clear that there are serious issues that need to be dealt with, and we will insist that they be dealt with," he added.
'Highly likely' Israeli troops killed American activist: IDF
The Israel Defense Forces (IDF) published the results of its initial inquiry into last week's killing of American Aysenur Ezgi Eygi in the West Bank.
"The inquiry found that it is highly likely that she was hit indirectly and unintentionally by IDF fire which was not aimed at her, but aimed at the key instigator of the riot," the IDF press release stated, referring to a period of reported unrest at the Beita Junction.
"Israel has sent a request to carry out an autopsy," it added. "The IDF expresses its deepest regret over the death of Aysenur Ezgi Eygi."
Eygi, 26, was a dual Turkish-American citizen and activist working for the International Solidarity Movement in the West Bank, working to protect local Palestinian farmers from attacks by Israeli settlers.
South Gaza polio vaccine drive reaches 446,000 children: WHO
The polio vaccination campaign in southern Gaza concluded on Monday with more than 446,000 children vaccinated since the drive began on Sept. 1, World Health Organization Director-General Tedros Adhanom Ghebreyesus said.
"Five health facilities will continue offering polio vaccination to make sure no child is missed," Ghebreyesus wrote on X. "We are grateful to the families for their cooperation, and to all vaccinators and health workers for their dedication."
The polio vaccination campaign is continuing elsewhere in Gaza, and Ghebreyesus said continued humanitarian pauses are "key" in facilitating the program. Preparations to expand the drive into the north of the devastated territory "are ongoing," he added.
"The children in Gaza deserve lasting peace, not just polio vaccines," Ghebreyesus said.
US expects 'transparent' probe into killing of American in West Bank
The State Department is "urgently working to get more information" on the killing of American citizen Aysenur Ezgi Eygi in the West Bank last week, Principal Deputy Spokesperson Vedant Patel told journalists at a Monday briefing.
Eygi, 26, was an activist working for the International Solidarity Movement and was shot dead in the West Bank village of Beita on Friday. The dual American-Turkish citizen was allegedly killed by Israeli troops.
Patel told reporters that "our partners in Israel are looking into the circumstances of what happened, and we expect them to make their findings public, and expect that whatever those findings are, expect them to be thorough and transparent."
IDF defends strike on Gaza's Khan Younis humanitarian area
The Israel Defense Forces (IDF) said a Monday night strike on tents in a designated humanitarian zone in the southern Gaza Strip targeted Hamas figures "directly involved" in the Oct. 7 attack.
The Hamas-run Gaza Civil Defense reported at least 40 people killed and at least 60 injured in the bombing. Search and recovery efforts were underway at the scene on Tuesday.
The IDF said Tuesday that its strike targeted "senior Hamas terrorists" in a "command and control center embedded inside the humanitarian area in Khan Younis."
Among those killed were Samer Ismail Khadr Abu Daqqa, the head of Hamas' aerial unit in Gaza, the IDF said.
Osama Tabesh, the head of the observation and targets department in Hamas' military intelligence headquarters, and Ayman Mabhouh, another "senior Hamas terrorist" were also hit, the force said.
"According to an initial review, the numbers published by the Hamas-run Government Information Office in Gaza, which has consistently broadcast lies and false information throughout the war, do not align with the information held by the IDF, the precise munitions used, and the accuracy of the strike," the IDF statement added.
At least 40 killed in strike on humanitarian area: Gaza Civil Defense
At least 40 people were killed and at least 60 people have been wounded after an Israeli strike in a designated humanitarian area of Khan Yunis, according to the Hamas-run Gaza Civil Defense.
The strike hit "a gathering of displaced persons' tents consisting of at least 20 inhabited tents," a Gaza Civil Defense spokesperson said early Tuesday morning local time.
The Israeli Air Force "struck significant Hamas terrorists who were operating with a command and control center embedded inside the Humanitarian Area in Khan Yunis," the Israel Defense Forces said in a statement.
Hamas changed 'some of the terms' of the hostage exchange: White House
The White House is remaining hopeful that talks for a cease-fire in Gaza and release of the remaining hostages can be salvaged after Hamas proposed new amendments to the deal following the killing of six hostages.
"Hamas did change some of the terms of the exchange. And that has made it more difficult for us to get there," National Security Communications Adviser John Kirby said at Monday’s press briefing.
"We still believe that, even for the new amendments that Hamas has made, that it's still worth an effort to try to see if we can't get back into a cease-fire negotiation," he added. "But we're not there right now."
Kirby would not say if President Joe Biden will be increasing pressure on Israeli Prime Minister Benjamin Netanyahu to accept a deal and potentially hold the transfer of weapons to Israel in order to secure a deal, similar to the recent decision by the United Kingdom.
"I can't think of anything we haven't put more pressure on ourselves than to try to get this deal," Kirby said. "We know how urgent this is. And we're working night and day to try to see if we can get a deal in place. Hamas is the main obstacle to this right now."

The Magen David Adom (MDA) -- Israel's emergency services -- said in a social media post that its personnel "located the site of the impact, as of now no casualties have been found."
Israeli media reported that a drone detonated after crashing into an apartment block.

Hundreds gather in Central Park for hostage vigil
The Hostages Families Forum Headquarters organized twin protests in Tel Aviv and New York on Sunday, as pro-cease-fire activists look to build pressure on Prime Minister Benjamin Netanyahu's government and American politicians.
Hundreds of people rallied in Central Park "to mourn six Israeli and American hostages murdered after 11 months in captivity," the Forum said in a press release.
Among the speakers were Gilad and Nitza Korngold -- the parents of hostage Tal Shoham who was abducted into Gaza on Oct. 7.
"The Red Cross has refused to help our loved ones while shamelessly requesting better conditions for the terrorists in Israel's imprisonment," they said, per the Forum's press release. "We ask everyone here to call your representatives and demand the release of our loved ones from captivity."
Moran Stela Yanai -- released in November 2023 after 54 days as a hostage in Gaza -- also spoke, telling attendees: "My brothers and sisters in captivity are hungry and in pain and in constant danger."
"We must find the strength to keep fighting for them and bring them home," she added, as quoted in the Forum's press release.

Jordanian border crossings partly reopened after shooting
Israeli and Jordanian authorities confirmed the partial reopening of border crossings on Monday following their closure due to the killing of three police officers at the Allenby Bridge.
An Israel Airport Authority spokesperson said the crossings at Yitzhak Rabin near Eilat, at the Jordan River near Beit Shean and at the Allenby Bridge would open for passenger traffic.
The media spokesman for the Jordanian Public Security Directorate said that King Hussein Bridge leading to the Allenby entry point would remain closed to freight traffic.
Meanwhile, Jordan's Interior Ministry said that its preliminary investigations into Sunday's shooting at the Allenby Bridge crossing confirmed that the alleged gunman was a Jordanian citizen named Maher Dhiyab Hussein Al-Jazi.
The alleged shooter -- whom Israeli security forces said they shot and killed -- was a resident of the Al-Husseiniyah area in Ma'an Governorate, and was crossing the bridge as a driver of a freight vehicle carrying commercial goods.
Al-Jazi acted alone, the ministry said, noting its investigation is ongoing. Authorities are attempting to organize the return of his body so he can be buried in Jordan.

Airstrikes hit Syrian scientific research center, state media says
Strikes targeted a Syrian scientific research area in the city of Masyaf in the Hama countryside on Sunday night, Syrian state media and the Syrian Observatory for Human Rights (SOHR) said.
"Ambulance vehicles rushed towards the center of the area" amid reports of casualties, the SOHR -- a U.K.-based war monitor -- said on its website.
Both Syrian state media and the SOHR attributed the strikes to Israel. The SOHR said Syrian anti-aircraft weapons intercepted some Israeli missiles.
There was no immediate confirmation on the number of casualties. At least 14 people were killed and 43 others were wounded, Syrian state news agency SANA reported. ABC News was not able to immediately confirm the reported casualties or whether they were military personnel.
ABC News asked the Israel Defense Forces for comment. Israel typically does not confirm or deny responsibility for strikes in Syria, where it has been engaged in a "shadow war" with Iran and its allies -- including the Lebanese Hezbollah militia -- for several years.

Nearly 70% of children in Gaza vaccinated against polio, health ministry reports
The polio vaccination campaign continued today in south Gaza, Khan Younis and Rafah, after early issues in the region when vaccines could not be properly distributed to the eastern side of Gaza.
The Palestinian Ministry of Health announced Sunday that 441,647 children in Gaza have received the first dose of the polio vaccine, so far.
This accounts for about 69% of the targeted population, according to the ministry.
According to the World Health Organization, 95% of children need to be vaccinated to prevent the spread of the disease effectively.
On Monday, vaccinations will be offered in northern Gaza where daily, eight-hour pauses in fighting and airstrikes will be instituted so children can be taken to one of the roughly 33 locations across Gaza City and north Gaza where the vaccine will be administered, according to the ministry.

Israel closes Jordan border crossings after deadly shooting
Israel closed on Sunday the two land crossings between Jordan and Israel, as well as the Allenby Bridge crossing between Jordan and the occupied West Bank, the Israel Airports Authority -- which oversees the crossings -- told ABC News.
The closures followed a shooting on Sunday morning at Allenby that killed three police officers.
The gunman -- who was shot dead by security forces -- came from the Jordanian side, but it was not immediately clear if he was affiliated with any militant group. Both Hamas and the Islamic Jihad issued congratulatory statements about the shooting.
Netanyahu condemned the attack, saying it was attributable to the "murderous ideology led by Iran's 'Axis of Evil'."
Israel did not say how long the closures would last. The Allenby crossing is one of the key entries through which goods destined for Gaza pass.
