Prominent Sudanese politician Hassan al-Turabi was buried Sunday in a cemetery east of the capital, Khartoum, following a funeral attended by thousands of mourners.
Turabi died Saturday of a heart attack at the age of 84.
He once played a major role in the 1989 coup that brought President Omar al-Bashir to power.
However, the two close allies later became bitter foes, and Turabi became the only Sudanese politician to support a warrant for Bashir's arrest by the International Criminal Court on charges of war crimes.
Turabi also at one time hosted al-Qaida leader Osama bin Laden, although the group was later expelled from Sudan under U.S. pressure in 1996. Turabi, who supported radical Islam in the 1990s, remade himself as a mainstream politician.
He was jailed several times after a power struggle and split with Bashir in 1999.
