Saudi Arabia has detained two senior members of the royal family.
According to two sources, those detained are King Salman's brother, Prince Ahmed bin Abdulazi and the king's nephew, Mohammed bin Nayef.
Reuters could not immediately determine the reasons behind the detentions.
Crown Prince Mohammed bin Salman, King Salman's son and the de facto ruler of the world's top oil exporter, has moved to consolidate power since ousting his cousin, Mohammed bin Nayef, as heir to the throne in a palace coup in 2017.
He arrested several royals in an anti-corruption campaign later that year.
The Wall Street Journal reported the detentions of the two royals related to an alleged coup attempt.
