Israel's emergency service said three people were killed in what police described as a "shooting attack" near the Allenby Crossing between the occupied West Bank and Jordan on Sunday morning.

"We found three men lying unconscious, with no pulse and not breathing, with gunshot wounds. Together with the IDF (Israeli military) medical team, we performed resuscitation efforts, but unfortunately, we had to declare their deaths on scene," a Magen David Adom emergency service statement said.

Israeli police said separately that an attacker had been "neutralized."
