Al-Houthi group announced two attacks against Saudi targets on Sunday. The al-Masirah channel of the Houthis said the group's gunmen targeted a BMW vehicle with a guided missile in the square of Suhar in Najran. They also targeted military carriers laden with Saudi soldiers east of Jabal Jafan in Jazan, south of the country.

The source said, quoting a military source, who declined to be named, said the two attacks killed a number of Saudi soldiers and that the Houthis had taken up arms.

The Saudi media reported that the coalition forces launched raids on sites and gatherings of Houthi fighters in the vicinity of the Directorate of Baqam in Saada, Yemen, resulting in deaths in their ranks.

The Al-Houthi group has recently stepped up its assaults on medium-range and medium-range missiles on Saudi targets, notably Jazan and Abha airports, while the group occasionally announces the killing of Saudi soldiers in clashes near the Yemeni border.

The Houthis control the capital Sana'a since September 2014, before expanding their dominance to several provinces. Since March 2015, a Saudi-led coalition has been supporting Yemeni government forces against the group in a war that has left a severe humanitarian crisis, the worst in the world, according to the United Nations.
