Is Saudi Arabia expanding its ballistic missile programme? Saudi Arabia is believed to be expanding its Chinese-designed ballistic missile arsenal as it faces an unprecedented barrage of missile and drone attacks from Yemen's Houthi forces. Satellite imagery analysed by American researchers suggests the kingdom is expanding its ballistic missile plant at al-Duwadimi in Riyadh Province to build larger solid-fuel missiles capable of carrying heavier payloads across greater distances.
