“They had a detailed discussion of Yemen conflict, and both parties endorsed the efforts of the new UN Special Envoy to Yemen Hans Grundberg and agreed to intensify diplomatic engagement with all relevant parties. Special Envoy Lenderking will remain in the region to follow up on the detailed discussions,” the official said. The official also said Sullivan thanked the crown prince for “Saudi Arabia’s hospitality in permitting thousands of at-risk Afghans to transit through Saudi territory” during Biden’s chaotic withdrawal from Afghanistan last month. Sullivan will be in Cairo on Wednesday for meetings with Egyptian officials that will include a discussion on Libya, White House National Security Council spokeswoman Emily Horne said in a statement. Sullivan will host Israel’s national security adviser, Eyal Hulata, in Washington on Oct. 5 for more discussions, she said.
