Carter had planned to make the visit tomorrow in an attempt to draw attention to the humanitarian situation in the war-battered territory. The trip included planned meetings with Hamas, the Islamic militant group that controls Gaza.
But the Elders, the group sponsoring the visit, expressed regret that the visit would not take place. It gave no explanation.
Israeli officials, who consider Hamas a terrorist group, have no plans to meet Carter. But Israeli Foreign Ministry spokesman Emmanuel Nahshon said Israel was prepared to allow Carter to visit Gaza, and the cancellation was not at Israel's request.
