A report on Al Masirah's website cited the Houthis' Missile Forces as announcing the launch of a Burkan H2 missile on Tuesday "in response to the heinous crimes committed by the US-Saudi aggression against the people of Yemen".
The missile had targeted a "meeting of the leadership of the Saudi regime in al-Yamama Palace in Riyadh", during which Crown Prince Mohammed bin Salman was expected to discuss the kingdom's annual budget, Al Masirah said.
The palace is the main headquarters of the king's office and the royal court.
Minutes later, Saudi state-run Al Ikhbariya TV reported that a missile had been intercepted south of the capital.
One video posted by a man who said he was in the Olaya district shows a white cloud above the city. The sound of an explosion can then be heard. Sky More
