Kuwait's Emir Sheikh Nawaf Al-Ahmad Al-Jaber Al-Sabah has been laid to rest after a prayer service at Bilal bin Rabah mosque.
His successor, Sheikh Meshal al-Ahmad al-Sabah, 83, attended the prayer service along with members of the ruling Al Sabah family and speaker of Kuwait's parliament.
Sheikh Nawaf, whose casket was draped in Kuwait's flag, was buried Sulaibikhat cemetery alongside his kin.
His three-year reign as emir was marred by ill health.
Sheikh Nawaf's predecessor and brother, Sheikh Sabah al-Ahmad al-Sabah, reigned for 14 years and shaped the Gulf state's foreign policy for two generations.
Dignitaries from around the world paid respects to Sheikh Nawaf, whose six decades in public service included minister of defence, interior, labour and deputy chief of the national guard.
