U.S. Secretary of State John Kerry and Palestinian Authority Chairman Mahmoud Abbas lunched in Riyadh on Monday and chatted about the prospects for peace -- among other topics -- after Abbas showed up "unexpectedly" Sunday in Saudi Arabia. Described as a "last-minute meeting" the two met at the Ritz-Carlton Hotel in the Saudi capital, together with their delegations. One of the main items of discussion during the meeting was the upcoming visit to the region of U.S. President Barack Obama, set to arrive in Israel on March 20.
