In a post on his Twitter account on Tuesday, Zarif said he was saddened by the passing away of Sheikh Sabah Al-Ahmad Al-Jaber Al-Sabah, the late Emir of Kuwait, who painted an image of moderation and equilibrium for Kuwait and the region.

Praying to God Almighty to have mercy on the late Emir’s soul, the top Iranian diplomat wished the Kuwaiti people and government prosperity, security, stability and progress under the new Emir.

Known as the “Wise Man of the Region”, Kuwait’s 91-year-old Emir died on Tuesday.

Born in 1929, Sheikh Sabah is widely regarded as the architect of modern Kuwait’s foreign policy.

Crown Prince Sheikh Nawaf al-Ahmad al-Sabah was named emir by the country’s cabinet to succeed his brother.
