Attempted coup in Umtata, Transkei

Explanation
On 22 November 1990, Colonel Craig Duli, a former member of the Transkei military council, led a coup attempt against Bantu Holomisa's Transkei military government with the support of members of the SA security forces. A group of heavily armed men attacked the Transkei Defence Force's Ncise base outside Umtata. By the end of the day, at least 15 men were dead, including Duli himself.
