RIYADH: Arab coalition forces intercepted a ballistic missile launched by the Houthi militia in Yemen towards Najran in Saudi Arabia on Thursday . Coalition spokesman Colonel Turki Al-Maliki said the missile launch was a systematic and deliberate attempt by the Houthis to target civilian objects and civilians. Attacks across the Yemen-Saudi border by the Houthi militias have escalated since late May. In June, their missiles reached the Saudi capital Riyadh. The coalition has since retaliated with airstrikes.
