Jordan’s king Abdullah sat down with King Salman on his arrival in Riyadh Tuesday. DEBKA’s sources report that the sour relations between Amman and Riyadh slumped still further as Jordanian lawmakers hurled abuse at Saudi Arab for its mild reaction to President Trump’s recognition of Jerusalem as the Israeli capital. The Saudi Crown Prince recently cut off Saudi financial aid to Jordan. Abdullah tried to pour oil on the quarrel and also to persuade the king to send a high-ranking delegation to the Islamic summit called by Turkish President Tayyip Erdogan, which is due to open in Istanbul Wednesday. Erdogan mocked Muslim rulers who have declined his invitation accusing them of being scared of Washington.
