Yemeni air defense units have shot down a Saudi reconnaissance drone in flight over a border area in the kingdom’s southwestern province of Jizan.

At least 15 people have lost their lives in fresh air raids conducted by Saudi warplanes on a strategic road linking the Yemeni port city of Hudaydah to the capital, Sana'a.

Yemen’s Houthi Ansarullah movement - which has joined hands with the country's army against a Saudi-led alliance of adversaries - says capital cities of the coalition will be “no longer safe" from missiles fired in retaliation for attacks on Yemen.
