Yemen's Houthi movement fired a ballistic missile toward Saudi Arabia on Saturday. A Saudi military spokesman says air defense forces intercepted the missile. It was fired toward the southern Saudi province of Najran. The Houthi's TV channel said the target of the short-range missile was a military base. There were no reports of casualties or damage. The Iranian-aligned Houthis have launched scores of missiles at the kingdom, deepening tensions between Riyadh and Tehran.
