National public holiday in Namibia
Cassinga Day is a national public holiday in Namibia remembering the Cassinga Massacre. Commemorated annually on 4 May, the date "remembers those killed in 1978 when the South African Defence Force attacked a SWAPO base at Cassinga in southern Angola". Commemorations are marked yearly by ceremonies at Heroes' Acre, outside of Windhoek. These ceremonies are attended by many important national political figures, including former presidents Sam Nujoma, Hifikepunye Pohamba and Hage Geingob.
