BEIRUT - Iranian state media on Wednesday called the appointment of Mohammed Bin Salman to the position of crown prince and successor to Saudi Arabia's King Salman as a "soft coup."
"Soft coup in Saudi Arabia/Son becomes the succesor of the father," read the headline on the Iranian state TV website.
The move is likely to rattle Iran's leadership, which has been critical of comments by Prince Mohammed last month that the "battle" should be taken into Iran.
Iran, which is predominantly Shi'ite Muslim, and Saudi Arabia, which is mostly Sunni, compete for power and influence across the region. The two countries support opposite sides in the conflicts in Syria and Yemen.
