Ward cites “multiple people who saw drafts of the plan” created by Kushner that would involve not just Israel and the Palestinians but also Saudi Arabia, Jordan, Egypt and the United Arab Emirates.

“What Kushner wanted... was for the Saudis and Emiratis to provide economic assistance to the Palestinians,” Ward wrote. “There were plans for an oil pipeline from Saudi Arabia to Gaza, where refineries and a shipping terminal could be built. The profits would create desalination plants, where Palestinians could find work, addressing the high unemployment rate.”

Ward said that the plan also included land swaps, where Jordan would give land to the Palestinian territories, and “in return, Jordan would get land from Saudi Arabia, and that country would get back two Red Sea islands it gave Egypt to administer in 1950.”

Speaking to Sky News Arabia, while in Warsaw last month, Kushner said the White House plan – expected to be presented sometime after the April 9 election in Israel – would focus on border issues.
