DOHA (Al Jazeera) – Yemen’s Houthi rebels say they have launched their biggest-ever military operation against Saudi Arabia. Eight drones and three ballistic missiles were fired towards Saudi Arabia since Monday, and the Houthis say they plan to launch more.

The Saudi-led coalition fighting the Houthis in Yemen says it has intercepted a ballistic missile headed towards Riyadh. A coalition spokesman says the attack was launched from the Yemeni capital, Sanaa, towards civilian targets in the kingdom.
