Saudi Arabia’s top military commander in its yearslong war in Yemen and his prince son have been removed from their posts along with other officials as part of an anti-corruption investigation, the kingdom said early on Tuesday.

The announcement attributed the actions to a referral by Saudi Crown Prince Mohammed bin Salman. A statement on the state-run Saudi Press Agency referred to “suspicious financial dealings monitored at the ministry of defence”.

Authorities also removed his son, Prince Abdulaziz bin Fahad bin Turki, from his position as the deputy governor of Saudi Arabia's al-Jouf region in the kingdom's northwest.

The kingdom is investigating four other officials as well, all on the orders of 84-year-old King Salman, the statement said.
