Israel-Gaza live updates: France, UK, Canada recognize Palestinian statehood

Two men were killed when a gunman opened fire at the Allenby Crossing that connects Israel and Jordan, the Israel Defense Forces said in a statement on Thursday.

Security forces killed the gunman who allegedly arrived at the crossing "in a truck transporting humanitarian aid from Jordan," according to the IDF.

A spokesperson for the Magen David Adom, Israel's national emergency medical services organization, said two men whose ages were approximately 60 and 20 years old were pronounced dead.

A statement from Hamas after the incident called it a "heroic operation."

The Allenby Crossing is one of five land border crossings between Israel and countries to the east and south, and is one of the crossing points for humanitarian aid destined for Gaza.

Jordan is investigating the shooting, its Foreign Ministry said in a post on X Wednesday.

"Jordan condemns and rejects as a violation of the law and a threat to the Kingdom's interests and its ability to deliver humanitarian aid to the Gaza Strip," the Ministry of Foreign Affairs says in the post.

The statement describes the driver who allegedly opened fire as “a civilian who began working three months ago as a driver to deliver aid to Gaza.”

According to the ministry, 22 Jordanian aid trucks crossed the bridge into Israel Thursday. The ministry said it is "following up ... on the conditions of the drivers who crossed the bridge today to deliver aid to Gaza, to ensure their immediate return to Jordan."

Hundreds of thousands of people have evacuated Gaza City in recent weeks after Israel announced plans to launch a major offensive into the strip's largest urban area -- an operation that began overnight into Tuesday.

People are traveling with their belongings piled on top of flat-bed trucks, in cars, by bike or on foot if necessary.

ABC News spoke with a man who said he was evacuating south on foot.

"This is not life. We're losing. We lost our homes, children and money," Ibrahem Hashem Shamallakh said. "There’s no transportation. There's nothing. I will shelter myself with a blanket if I have to."

Joumana Mabhouh has been displaced several times during the war, she said.

"To displace from north to south, it's not just losing your house, it's losing Gaza itself," Mabhouh said. "We are really tired of these difficult conditions in the Gaza Strip."

Mabhouh said people are traveling south without "basic food supplies."

"As you can see people coming from the north, from north to south without basic food supplies, and the mothers are trying to calm their children with empty hands," she said.

About 400,000 people had evacuated Gaza City as of Wednesday, according to the Israel Defense Forces. Some 600,000 people are thought to remain in Gaza City.
