Oman declared three days of official mourning with flags to be flown at half-mast for 40 days for Sultan Qaboos, 79.
State television broadcast images of the funeral procession driving down a road lined with palm trees. The casket, draped in the Omani flag, was then carried into Sultan Qaboos Grand Mosque in the capital Muscat, where prayers were being held.
