Manama - White House senior adviser Jared Kushner said that prosperity for the Palestinians is not possible without a fair political solution but that agreement on an economic pathway forward was a necessary precondition for Israeli-Palestinian peace.

Kushner was speaking at the opening of a workshop in Bahrain to showcase the economic portion of Washington’s long-awaited Arab-Israeli peace plan, a $50 billion development blueprint unveiled this week that has faced sharp criticism from Palestinians and Arabs across the region.

Kushner, the son-in-law of US President Donald Trump, said the political component of the plan would not be discussed at the event.
