Footage filmed by a tourist shows a giraffe taking the weight of its hooves and resting on its stomach in the sunshine as a male antelope approaches it.
At first, it seems that the horned herbivore is just after a cuddle as it gently nuzzles it head into the giraffe’s chest.
But suddenly things turn violent.
The antelope steps back and rams its head hard into the giraffe’s neck, causing the lanky creature to rise to its feet.
As shocked children and parents scream, the giraffe angrily gallops away, disgusted by the antelope’s boisterous behaviour.
But the hot-tempered antelope is still after a fight.
It chases the giraffe with its horns rammed firmly in the poor creature’s stomach until it trips over some rocks and lands flat on its face.
The antelope menacingly pins its victim to the ground before deciding it prefers a fair fight and uses its horns to scoop the giraffe back up onto its legs.
Seeing its chance to escape, the giraffe gallops away from its attacker to a herd of its own, hoping his giraffe pals will help him.

But rather than rush to its rescue, the seven-strong herd all turn and scarper as the antelope charges towards them.
The incident happened at Rotterdam Zoo in Netherlands on Tuesday (June 13) and is especially unusual as the pair have lived in the same enclosure for years and have never had problems in the past.
A much more heartwarming zoo clip went viral earlier this year as the world’s most famous giraffe, April, gave birth in New York.
The creature’s labour was live streamed and saw millions tune in.
