Three Israelis were shot and killed on Sunday at the border crossing between the West Bank and Jordan, Israeli officials said, in what appeared to be an attack linked to the 11-month-old war in Gaza.
The military said the gunman approached the Allenby Bridge Crossing from the Jordanian side in a truck and opened fire at Israeli security forces, who killed him in a shootout.
Israel's Magen David Adom rescue service said the three killed were all men in their 50s.
A spokesperson with the Israel Airports Authority, which oversees borders, said the attacker was Jordanian.
Jordan is investigating the shooting, its state-run Petra News Agency reported.
The Western-allied Arab country made peace with Israel in 1994 but is deeply critical of its policies toward the Palestinians. Jordan has a large Palestinian population and has seen mass protests against Israel over the war in Gaza.
The Allenby crossing over the Jordan River, also known as the King Hussein Bridge, is mainly used by Palestinians and international tourists, as well as for cargo shipments.
The crossing has seen few security incidents over the years, but in 2014 Israeli security guards shot and killed a Jordanian judge who they said had attacked them.
Authorities in Israel and Jordan said the crossing was closed until further notice. Israel later announced the closure of both of its land crossings with Jordan, near Beit Shean in the north and Eilat in the south.
Israeli Prime Minister Benjamin Netanyahu condemned the attack and linked it to Israel's larger conflict with Iran and allied militant groups, including Hamas in Gaza and Hezbollah in Lebanon.
The Israeli-occupied West Bank has seen a surge of violence since Hamas' October 7 attack out of Gaza triggered the war there.
Israel has launched near-daily military arrest raids into dense Palestinian residential areas, and there has been a rise in Israeli settler violence and Palestinian attacks on Israelis.
Also on Sunday, loved ones mourned Aysenur Ezgi Eygi, an American-Turkish woman who was shot dead on Friday in the West Bank. She had been demonstrating against Israeli settlements there.
The White House has said it was deeply disturbed and called on Israel to investigate, while her family seeks an independent investigation.
