The Houthi–Saudi conflict is an ongoing armed conflict involving the Armed Forces of Saudi Arabia and Houthi forces in Yemen and along the Saudi–Yemeni border, including parts of Asir, Jazan, and Najran in Saudi Arabia and Saada, Al-Jawf, and Hajjah in Yemen. The conflict began following the Saudi-led intervention in Yemen in 2015.
Background
During their 2004 conflict with the government of Yemeni President Ali Abdullah Saleh, the Houthis accused Saudi Arabia of pressuring Saleh to take action against their community and of providing him with financial support. This accusation was denied by Saleh, and was not acknowledged by Saudi Arabia. Yahya al-Houthi, early in July 2008 indicated Saudi Arabia pressured Saleh to fight Zaydis and Shia Yemeni tribes.
Houthi forces and Yemeni Army units aligned with the Houthis deployed teams equipped with anti-tank guided missiles (ATGMs) to target military vehicles and positions. BM-21s and BM-27s would then target military bases and lay landmines along routes connecting with the Saudi Arabia–Yemen border. Meanwhile, pro-Houthi special forces would assault the border outposts, while motorcycle mounted teams armed with RPG-7s and US-made M47 Dragons infiltrated the Saudi rear. Columns of Saudi Arabian Army (RSLF) forces drive into unknown minefields and ambush places not directly hit by the fighting. Some raiding parties deployed into Saudi Arabia were armed with portable air defense systems (MANPADS), as well as M167 Vulcan towed anti-aircraft cannons. In the first year of the war, they damaged numerous attack helicopters of the RSLF and the Royal Saudi Navy (RSNF), forcing their crews to keep their distance.
On 26 March 2015, a Saudi-led coalition that included the United Arab Emirates began an air campaign in Yemen after Houthi forces captured Sanaa and advanced towards Aden. The coalition also imposed a naval and air blockade on Yemen beginning in March 2015, severely restricting the flow of food, fuel, and medicine, according to Human Rights Watch. Human Rights Watch reported that these restrictions, including port closures and delays to commercial shipments, exacerbated shortages of essential goods and put civilians at serious risk. It also documented cases in which Houthi-Saleh forces obstructed humanitarian assistance.
Conflict
2015
As a result of the Saudi-led intervention in Yemen, the Houthis shelled the Saudi city of Najran on 5 May 2015. Saudi authorities temporarily closed local schools, and the Najran Regional Airport.
On 26 March 2015, Saudi-led coalition airstrikes hit 14 houses in the Bani Hawat neighbourhood near Sanaa International Airport. Amnesty International reported that at least 25 people were killed, including six children, based on interviews with hospital staff and eyewitnesses. At the time, it was unclear whether any of those killed were combatants.
In a June 2015 report, Human Rights Watch documented 12 coalition airstrikes in Saada between 6 April and 11 May that damaged or destroyed homes, five markets, a school, and a petrol station. The attacks killed 59 people, including at least 35 children, according to the report. Human Rights Watch said it could not independently confirm the civilian status of everyone killed, but found no evidence that the sites its researchers examined were being used for military purposes.
2016
Saudi Arabia stated on 25 July 2016 that clashes resulted in the deaths of five Saudi border guards.
Regular clashes resumed on 11 August, after a one-year ceasefire between the Saudis and Houthis at the Saudi–Yemeni border expired. The Houthis gained entrance into Najran city. On 16 August, Houthi shelling killed seven civilians in an industrial zone in Najran. On the 26th, a power station near the border was hit by a Houthi rocket. A 3-year-old boy was killed by subsequent debris, and his 9-year-old brother was injured. On the 28th, Saudi officials stated that a rocket fired from Yemen hit a family's home in Saudi Arabia, killing two children and wounding five others.
On 15 August 2016, a Saudi-led coalition airstrike hit Abs Hospital in Yemen’s Hajjah governorate, a facility supported by Doctors Without Borders (MSF). The attack killed 19 people, including an MSF staff member, and injured 24 others. MSF said it had repeatedly shared the hospital’s GPS coordinates with the parties to the conflict, including the Saudi-led coalition.
Following the attack, MSF withdrew its staff from six hospitals in northern Yemen, citing security concerns. The organisation said the withdrawal left an already vulnerable population with reduced access to healthcare.
On 12 September, Saudi Arabia stated that a Houthi mortar killed three Saudi soldiers and wounded two in Najran Province, and also that there had been over five hundred Houthi casualties since the start of the conflict in the province. On 24 September, Houthi Major-General Hassan Almalsi was killed while his squad was attempting to infiltrate into Najran Province.
On 16 September 2016, The Guardian reported that the Yemen Data Project had recorded more than 8,600 air attacks carried out by the Saudi-led coalition between March 2015 and the end of August 2016. Of these, 3,158 were recorded as hitting non-military sites and 3,577 as hitting military sites, while the status of 1,882 attacks remained undetermined. The dataset included attacks on residential areas, markets, schools, hospitals, and mosques. Saudi Arabia disputed the figures, describing them as exaggerated and questioning the methodology used to compile the data.
On 12 October, Salafist fighters, including Salafist leader Bassam al-Mehbar, took control of al-Buqa' border crossing in Yemen's Saada Governorate, with the help of Saudi air support.

In January 2016, a UN panel of experts identified 119 Saudi-led coalition air sorties associated with potential violations of international humanitarian law. Its report documented attacks affecting civilian objects, including residential areas, medical facilities, schools, markets, food warehouses, and transport routes.
The report also documented attacks on food-storage facilities and domestic transport routes, which were important for the movement of essential supplies within Yemen.

The Houthis claimed the brigades were preparing for a major attack against the Houthis in retaliation to the attack on Abqaiq and Khurais oil facilities, but were entrapped by the Houthis. The Saudis then allegedly conducted airstrikes targeting the Saudi captives but the spokesman assured the families of the captives that they were able to hide and protect them from the Saudi airstrikes.
