Israel-Gaza updates: Police killed in border shooting, authorities say

The Hostages and Missing Families Forum touted Saturday night's pro-cease-fire protest as "Israel's largest-ever rally," reporting the attendance of "over 500,000 people in Tel Aviv and 250,000 across Israel."

Demonstrators flooded downtown Tel Aviv to again demand that Prime Minister Benjamin Netanyahu's government reach a hostage-release deal with Hamas. The recent deaths of six hostages in Gaza have reinvigorated the pro-cease-fire movement in Israel and put pressure on the prime minister.

Among the speakers were two former Gaza hostages. Andrey Kozlov -- rescued from Hamas captivity by the Israel Defense Forces in July -- told marchers: "We cannot allow this disaster to keep happening, we have to demand our leaders to do whatever it takes and do the right thing."

Kozlov spent two months in captivity with Alex Lobanov, who was among the six hostages recently found dead in a tunnel in the south of the strip. "We must demand our leaders to agree to this chance even if it is difficult," Kozlov said on Saturday.

"We must demand no one forgets the hostages, no one ignores them, no one leaves them to die. Their time is running out, we see it, we feel it. Bring them back home now."

Danielle Aloni -- also kidnapped on Oct. 7 -- said in her address: "The time has come for courageous decisions. A hostage deal, supported by the international community, and led by President Biden, offers the only chance for their safe return."

"This is not just Israel's responsibility; this is a global humanitarian crisis. The world must stand united to bring them home. It's not just about saving lives, it's about restoring humanity and justice. Prime Minister Netanyahu, seal the deal. Now."

Three people were killed in a "shooting attack" at the Israeli-controlled Allenby Bridge border crossing between the West Bank and Jordan on Sunday morning.

"There are several casualties at the scene, and the shooter has been neutralized," the police said in a statement.

A spokesperson for the Magen David Adom (MDA) -- Israel's national emergency service -- said that three people were killed.

"After resuscitation efforts, MDA paramedics and EMTs, in cooperation with an IDF medical team, have pronounced the deaths of three men, approximately 50 years old, with gunshot wounds," the spokesperson said.

The IDF confirmed that the three people killed were Israeli citizens. "A terrorist approached the area of the Allenby Bridge from Jordan in a truck, exited the truck, and opened fire at the Israeli security forces operating the bridge," the IDF said in a statement.

"The terrorist was eliminated by the security forces, three Israeli civilians were pronounced dead as a result of the attack," the statement added. "IDF soldiers were dispatched to the scene and are currently operating to rule out the suspicion of the truck being rigged with explosives."

The IDF reported approximately 50 projectiles crossing into Israel from Lebanon overnight into Sunday and confirmed it struck "Hezbollah military structures" in several parts of southern Lebanon.

The IDF reported three waves of projectiles spread over the early hours of Sunday morning. Those not intercepted fell in open areas and did not cause any injuries, the force said in a statement.

In addition to its airstrikes in several parts of southern Lebanon, the IDF said it "struck and eliminated terrorists from the Amal terrorist organization that operated within a Hezbollah military structure" in the southern village of Froun.

Lebanese authorities accused Israel of killing three emergency workers in the strike on Froun. Lebanon's Health Minister Firas Abiad described the incident as a "blatant and reprehensible attack, which flouts international laws and norms."

Three Palestinians were killed and dozens more were injured after the Israel Defense Forces conducted an airstrike on a school in Gaza City.

A Gaza Civil Defense spokesperson says there were displaced families at the school.

The IDF said it targeted terrorists who were using the school as a "command center."

This is the third school the IDF has claimed responsibility for striking this month, and the 28th school since June 1st.
