Foreign Secretary Boris Johnson said:
I am shocked and horrified by the attempted missile strike on Riyadh which was a deliberate targeting of a civilian area. The United Kingdom remains committed to supporting Saudi Arabia as it faces regional crises and security threats. We condemn in the strongest terms this attempted attack and the actions of those involved. British Nationals in Saudi Arabia should continue to follow FCO Travel Advice.
