Three Israeli men were killed in a terrorist shooting attack at the Allenby Bridge Crossing between Jordan and the West Bank on Sunday morning, authorities said.

The attack was carried out by a truck driver who had arrived from Jordan. The crossing, also known as the King Hussein Bridge, is the West Bank’s sole crossing with Jordan.

According to the military and Israel Airports Authority officials — the latter of which manages the land crossing — the gunman got out of the truck he was driving during an inspection at the terminal and opened fire at several of the crossing’s workers, killing three.

IAA security guards returned fire at the terrorist, killing him. The identity of the gunman was not immediately known, although he was believed by Israeli authorities to be Jordanian.

The Magen David Adom ambulance service said its medics treated the three men, all in their 50s, at the scene, but were forced to declare their deaths. The victims were not immediately named.

Footage circulating online purported to show the moment of the attack.

The Israel Defense Forces described the shooting as a terror attack. It published an image of the handgun used by the terrorist.

The IDF suspected that the truck in which a terrorist arrived was possibly rigged with explosives. Sappers were dispatched to the scene to check the truck for bombs, the military said.

Israeli and Jordanian authorities both announced that the crossing had been closed until further notice following the deadly shooting attack.

The Jordanian interior ministry also said that authorities had begun an investigation into the attack.

The IAA said that in addition to the closure of Allenby Bridge, the other land crossings with Jordan — the Rabin Crossing near Eilat and the Jordan River Crossing near Beit She’an — were closed at the request of security authorities.

Palestinians can only use the Allenby Bridge Crossing to enter Jordan from the West Bank, while Israelis generally use the Rabin and Jordan River crossings.

Violence in the West Bank has surged in the past year, following the October 7 Hamas terror onslaught in southern Israel, in which some 1,200 people were massacred and 251 were taken hostage.

Since October 7, troops have arrested some 5,000 wanted Palestinians across the West Bank, including more than 2,000 affiliated with Hamas.

According to the Palestinian Authority health ministry, more than 670 West Bank Palestinians have been killed in that time. The IDF says the vast majority of them were gunmen killed in exchanges of fire, rioters who clashed with troops or terrorists carrying out attacks.

During the same period, 32 people, including Israeli security personnel, have been killed in terror attacks in Israel and the West Bank. Another six members of the security forces were killed in clashes with terror operatives in the West Bank.
