Illness and death
From 2014, Qaboos suffered from colon cancer, for which he received treatment.  On 14 December 2019, he was reported to be terminally ill with a short time to live after his stay for medical treatment in UZ Leuven in Belgium and returned home because he wanted to die in his own country. He died on 10 January 2020 at the age of 79 at his personal residence, Bait Al-Baraka, just outside Muscat. The following day, the government declared three days of national mourning and said the country's flag would be flown at half-staff for a period of 40 days and declared the halt of official work in the public and private sectors for three days. Kuwait, Saudi Arabia, Qatar, United Arab Emirates, Bahrain, Lebanon, and Egypt all declared three days of mourning; India and Bangladesh declared one day of mourning. The United Kingdom lowered flags to half-mast as a sign of respect.
