Multiple explosions were heard in Riyadh, the capital of Saudi Arabia, on Monday, according to Reuters and AFP news agencies. Reports indicate at least three explosions were audible, with AFP reporters confirming multiple incidents. These explosions followed a warning from Saudi Arabia regarding a potential hostile threat to Riyadh. The Saudi-led coalition stated they destroyed a ballistic missile en route to the city. King Khalid International Airport in Riyadh has been closed for several days following at least three attacks in recent days. Tragically, at least 18 people have been killed and hundreds injured as a result of the attacks.
