Saudi social media users launched a campaign against a Palestinian cartoonist working at Al Jazeera after the news site published a piece which criticised Saudi Crown Prince Mohamed Bin Salman.
Following the dramatic decline in oil prices, cartoonist Mahmoud Abbas, who lives in Sweden, drew a caricature showing an oil barrel rolling fast towards a man who is clearly from the Gulf.
The caricature aroused the anger of the Saudi social media army who considered it an attack on the crown prince.
The hashtag "Palestine is not my issue" began to trend on Twitter as a result.
"Do not incite Saudis by targeting those they love: country, resources and rulers. At first, you have to purge your country from the traitors who are trading with your [the Palestinian] cause," one user wrote.
Others threatened the cartoonist and published personal information about him and his family, describing him as a "terrorist".
