A major showdown awaits Palestinian leader in Riyadh

Palestinian Authority Chairman Mahmoud Abbas is on his way Tuesday to Riyadh where he faces a stern demand to break away from the Turkish-Qatari-Jordanian line-up fighting US political steps in the region. DEBKAfile reports that Saudi Crown Prince Muhammed bin Salman will not give way on this demand and, if Abbas holds out, the showdown could end in the Saudis cutting off assistance to the Palestinian Authority.
