U.S. President Donald Trump’s son-in-law Jared Kushner is due in Israel next week for discussions on Washington’s efforts to move forward with its Gaza initiative, according to an Axios report, with Board of Peace representative Nickolay Mladenov expected to join the visit.

The planned trip would be Kushner’s first visit to Israel since January, the news outlet said in a report citing five sources familiar with the plan.

Kushner and Mladenov intend to meet Prime Minister Benjamin Netanyahu and other Israeli officials in an effort to reach understandings on implementing the plan’s next stages over the coming months, it added.

Netanyahu on Sunday rejected a 15-point Gaza plan approved by the Board of Peace and accepted by Hamas, insisting that the Palestinian group must be disarmed before any further Israeli withdrawal from the enclave.

His remarks came despite a roadmap issued by the board on July 31 which calls for Hamas’ disarmament and a gradual Israeli withdrawal to proceed in parallel.
