Tribesmen loyal to the Houthi movement hold their weapons as they attend a gathering to mark 1000 days of the Saudi-led military intervention in the Yemeni conflict, in Sanaa, Yemen December 21, 2017.

Yemen lies beside the southern mouth of the Red Sea, one of the most important trade routes in the world for oil tankers, which pass near Yemen's shores while heading from the Middle East through the Suez Canal to Europe.
Saudi air defenses on Thursday intercepted a "ballistic missile" fired by Yemen's Houthi militia group towards the Saudi city of Najran near the Saudi-Yemen border, Saudi news broadcaster Al-Arabiya has reported.
Last Friday, social networking sites shared a number of pictures of an intercepted Houthi missile in the Najran area.

Al-Maliki continued to say the Houthis are using the port of Hudaydah as a means for "smuggling advanced weaponry, but also as a launch pad for attacks on global ships".
The war has killed more than 10,000 Yemenis, mostly civilians, and pushed the country to the brink of mass starvation.
