The Houthi–Saudi Arabian conflict is an ongoing armed conflict between the Royal Saudi Armed Forces and Iran-backed Yemeni Houthi forces that has been taking place in the Arabian Peninsula, including the southern Saudi regions of Asir, Jizan, and Najran, and northern Yemeni governorates of Saada, Al Jawf, and Hajjah, since the onset of the Saudi Arabian-led intervention in Yemen in 2015.
