Saudi Arabia

Cluster Munition Ban Policy

Last updated: 05 September 2023

Summary: Non-signatory Saudi Arabia has not commented on the humanitarian concerns raised by cluster munitions or taken any steps to join the Convention on Cluster Munitions. Saudi Arabia has participated as an observer at meetings of the convention, most recently in September 2019. Saudi Arabia abstained from voting on the key annual United Nations General Assembly (UNGA) resolution promoting the convention in December 2022.

Saudi Arabia is not known to have produced or exported cluster munitions, but has imported them and possesses a stockpile. Saudi Arabia used cluster munitions in 2015–2017 in Yemen, during its military operation against Ansar Allah (Houthi) forces.


The Kingdom of Saudi Arabia has not acceded to the Convention on Cluster Munitions.

Saudi Arabia has shown interest in the convention, but has not taken any steps to accede to it. In 2017, Saudi Arabia acknowledged the humanitarian rationale behind the convention, and said that the government was considering its position on joining.[1]

Saudi Arabia attended several meetings of the Oslo Process, including the Dublin negotiations in May 2008, as an observer.[2] Yet Saudi Arabia did not participate in the Oslo Signing Conference in December 2008 or explain why it did not sign the convention.

Saudi Arabia has participated as an observer at meetings of the convention, most recently attending the Ninth Meeting of States Parties in Geneva in September 2019.[3] Saudi Arabia was invited to, but did not attend, the Tenth Meeting of States Parties held in Geneva in August–September 2022.

In December 2022, Saudi Arabia abstained from voting on a key UNGA resolution urging states outside the Convention on Cluster Munitions to “join as soon as possible.”[4] Saudi Arabia has not explained why it has abstained from the vote on the annual UNGA resolution since it was first introduced in 2015.

Saudi Arabia has voted in favor of UNGA resolutions condemning use of cluster munitions in Syria.[5]

Saudi Arabia is not party to the Mine Ban Treaty. It is party to the Convention on Conventional Weapons (CCW).

Production and transfer

Saudi Arabia is not known to have produced or exported cluster munitions, but has imported them.

The United States (US) suspended its sales and deliveries of cluster munitions to Saudi Arabia in May 2016, after evidence that Saudi Arabia had used cluster munitions in civilian areas of Yemen.[6]


Saudi Arabia has not provided information on the quantities and types of cluster munitions in its stockpile, which includes cluster munitions manufactured in Brazil, the United Kingdom (UK), and the US.

Saudi Arabia purchased 1,300 CBU-105 Sensor Fuzed Weapons manufactured by US company Textron Defense Systems in 2013, after concluding a previous deal in 2011 for 404 CBU-105s.[7] Other US transfers of cluster munitions to Saudi Arabia include 1,000 CBU-58 and 350 CBU-71 cluster bombs between 1970 and 1995.[8] In 1991, the US concluded agreements to provide 1,200 CBU-87 Combined Effects Munitions cluster bombs to Saudi Arabia, and to provide another 600 CBU-87 cluster bombs in 1992.[9]

The Royal Saudi Air Force (RSAF) has UK-produced BL-755 cluster bombs in service, according to Jane’s Information Group.[10] The last UK transfer of BL-755 cluster munitions to Saudi Arabia occurred in 1989.[11]

Saudi Arabia also possesses Hydra-70 and CRV-7 air-to-surface rockets, but it is not known whether its stocks include the M261 submunition variant.[12]


There has been no evidence or allegations of cluster munition use by Saudi Arabia in 2022 and the first half of 2023.

Saudi Arabia has used cluster munitions in the past, most recently in 2015–2017 in Yemen during the military operation that it led against Ansar Allah (Houthi) forces.[13]

Previous use in Yemen

From 2015 to 2017, a Saudi Arabia-led coalition of states used seven types of air-delivered and ground-launched cluster munitions in Yemen. The cluster munitions were manufactured and exported by three countries.

A December 2016 statement by the Saudi Arabia-led coalition did not deny using cluster munitions in Yemen and argued that “international law does not ban their use.”[15] Saudi Arabia’s spokesperson said that the coalition used a CBU-105 Sensor Fuzed Weapon once, in April 2015, but claimed that they are not prohibited weapons.[16] The United Arab Emirates (UAE) also stockpiles CBU-105s, but denied using them in Yemen.[17]

The Saudi Arabia-led coalition’s use of BL-755 cluster munitions marked the first recorded use of UK-made cluster munitions since the Convention on Cluster Munitions—to which the UK is a State Party—took effect in 2010.[18] Saudi Arabia committed to stop using BL-755 cluster munitions in December 2016.[19]

In September 2016, States Parties to the Convention on Cluster Munitions issued a joint declaration stating that they “condemn any use by any actor” and expressing deep concern at “any and all allegations, reports or documented evidence of the use of cluster munitions, most notably in Syria and Yemen in the past year.”[20]

Other use

The RSAF conducted airstrikes and Saudi military forces intervened on the ground in late 2009 in Saada governorate, after fighting between the Yemeni government and Houthi rebels intensified and spilled over the border into Saudi Arabia.[21] Remnants of CBU-52 cluster bombs were filmed near Saada city.[22]

In 1991, both Saudi and US forces used cluster munitions on the territory of Saudi Arabia in response to an incursion by Iraqi armored units in the prelude to Operation Desert Storm. During the battle of Khafji in January 1991, Saudi Arabia attacked Iraqi forces with cluster munitions fired from ASTROS multi-barrel rocket launchers, which Saudi Arabia had acquired from Brazil.[23] The weapons reportedly left behind a significant number of unexploded submunitions.[24]

As a recipient of US cluster munitions, Saudi Arabia has agreed to use cluster munitions “only against clearly defined military targets and…not be used where civilians are known to be present or in areas normally inhabited by civilians.” This language is required by a US law restricting the export of cluster munitions.

Some States have undertaken a commitment to refrain from using cluster munitions by becoming party to the 2008 Convention on Cluster Munitions.

[16] Brig.-Gen. Ahmed Asiri informed CNN on 4 May 2015 that Saudi Arabia had used CBU-105 cluster bombs in Yemen against armored vehicles only, describing it as an “antivehicle weapon” and stating, “We do not use it against persons. We don’t have any operation in the cities.” Ben Brumfield and Slma Shelbayah, “Report: Saudi Arabia used U.S.-supplied cluster bombs in Yemen,” CNN, 4 May 2015. Asiri also acknowledged to the Financial Times that Saudi forces had used a US-made weapon that engages targets such as armored vehicles and is “equipped with self-destruct and self-deactivation features” but did not call it a cluster munition and argued that it was being used to target vehicles and not people. “Saudi Arabia accused of using cluster bombs in Yemen airstrikes,” Financial Times, 3 May 2015. Asiri told Bloomberg that the categorization of the cluster munitions as banned “isn’t correct.” Glen Carey, “Saudis Deny Sending Troops to Yemen, Reject Cluster-Bomb Report,” Bloomberg, 3 May 2015. Asiri further informed CNN on 11 January 2016 that Saudi Arabia had used cluster munitions against concentrated rebel camps and armored vehicles, but never against civilian populations.
