Houthi–Saudi Arabian conflict

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.

Over the course of the conflict the Houthis have carried out attacks on military bases and outposts in Saudi Arabia.

Background

In their 2004 conflict against the government of Yemeni President Ali Abdullah Saleh, the Houthis accused Saudi Arabia of pressuring Saleh to crack down on their community, and of funding him with 25 billion. This accusation was denied by Saleh, and was not acknowledged by Saudi Arabia. The Houthis and pro-Houthi Yemen army units were deploying effective tactics. Usually, they would first deploy teams equipped with anti-tank guided missiles (ATGMs)—like Russian made 9M113 Konkurs, 9M113 Kornet-Es and a few BGM-71 TOWs—to take out specific vehicles or bunkers. BM-21s and BM-27s would then target nearest military bases and lay landmines along routes connecting with the Saudi Arabia–Yemen border. Meanwhile, pro-Houthi special forces would start assaulting the border outposts, while motorcycle mounted teams armed with RPG-7s and US-made M47 Dragons would infiltrate into the Saudi rear. Columns of Saudi Arabian Army (RSLF) forces would thus drive into unknown minefields, or rush into ambushes at places not directly hit by the fighting. Some raiding parties deployed into Saudi Arabia were armed with man-portable air defence systems (MANPADS), as well as M167 Vulcan towed anti-aircraft cannons. Although exact details of the effectiveness of either remain evasive, during the first year of the war they damaged numerous attack helicopters of the RSLF and the Royal Saudi Navy Forces (RSNF), thus forcing their crews to keep their distance.
