A Saudi Aramco building in Riyadh was hit by falling shrapnel after air defences shot down an incoming projectile on Sunday 8 November, Al Jazeera reports.
Al Jazeera places the incident in the context of fighting with Yemen's Houthi rebels. There has been no official confirmation of where the projectile came from.
Earlier, Reuters reported that a tower in the King Abdullah Financial District was damaged by a projectile. It did not identify the origin. The two reports may describe the same incident, but this has not been confirmed.
Al Jazeera's account has not been independently verified.
