Friends and foes gather in Oman to mourn Sultan Qaboos

World and regional leaders, many at odds with one another, met Oman's new ruler on Sunday to offer condolences for the death of Sultan Qaboos whose quiet diplomacy during five decades in power helped calm regional turbulence.The rulers of Qatar and the United Arab Emirate, which are locked in a protracted dispute, were among those who visited the royal palace in Muscat as was the foreign minister of Iran, which is an arch-foe of U.S.-allied Saudi Arabia and the UAE.
