Israel-Gaza live updates: Aerial 'infiltration' attack reported in northern Israel

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.

The Israel Defense Forces (IDF) reported the killing of a Hamas rocket commander in an airstrike last week.

The IDF wrote on social media on Sunday that its Southern Command "eliminated" Raef Omar Salman Abu Shab -- the commander of the rocket unit of the eastern Khan Younis Brigade -- in an airstrike on Tuesday

The commander was "responsible for launching rocket barrages from the area of Khan Younis toward southern and central Israel since the start of the war," the IDF said.
