Cuban, Angolan, and South African propaganda during Angolan Civil War

It's common knowledge that the Cuban military intervention in Angola wasn't just about quelling factional strife in that African country but also indirectly weakening the apartheid government in South Africa, and that Fidel Castro's strong stance against racism endeared him to express solidarity with South Africa's anti-apartheid icon Nelson Mandela. Therefore, I'm wondering if the Cuban and Angolan governments as well as the apartheid regime in South Africa spewed propaganda during the Angolan Civil War. Here are some forms of propaganda I think were spewed by the Cubans, Angolans, and South Africans during the conflict:

1. Propaganda posters issued by the apartheid government calling Afro-Cuban men and women in uniform as well as Angolan troops the "Black Death" (not a reference to the 14th century bubonic plague, but to the skin color of Angolan and Afro-Cuban servicepeople) just because the apartheid rulers considered themselves defenders of Judeo-Christian values in the face of the communist ideology embraced by the Castro regime and Angolan government.
2. A propaganda mural on the rear facade of a Cuban elementary school facing a sports field and playground in the school wishing Cuban troops success in their fight against South African troops in Angola.
3. Cuban and Angolan propaganda posters depicting South African troops as ferocious animals with Nazi symbols on their upper arms and helmets.
4. An Afro-Cuban servicemen holding a black South African girl in his left arm while using his foot to choke a South African soldier to death on the neck.

During the final spurt of the Cold War, the conflict in Angola was the 'playing field' for a surge in propaganda warfare.

Most of it was the kind of propaganda that simply took the horrific events and created a narrative to vilify the opposition. But some of it was a more bold application of direct fabrication of outright lies...

... and it bears mentioning that the first signs of the international press core having adopted a 'prostitution' state, propagating and profiteering by simply embracing the sources' efforts to just "report whatever they were paid to say."

(Sort of like today, where they are handed material and then reporters pretend they 'investigated it' - calling it "journalism" or better yet "advocacy journalism.")

There was one tale of a group of Cuban and Angolan (MPLA) troops who would attack villagers and then distribute young and older girls for sexual assault... The atrocity was characterized as the barbarism one could expect from the "Commie bad guys" but this time, through circumstance, those soldiers were eventually captured and the village women lined them up and vengefully executed them all ... an ironic 'feel good' ending.

Only, it never happened. At all. Not even the villagers could understand where that story came from... turns out, it came from Western Press... who defended themselves by saying "we never actually said it happened." But that, of course, is history, and it could never happen again, right?
