Summary: Non-signatory Sudan has expressed interest in joining the convention but has not taken any tangible steps to accede. Sudan has participated as an observer in several meetings of the convention, most recently in September 2018. It voted in favor of a key United Nations (UN) resolution on the convention in December 2018.
There is no evidence to indicate that Sudan has produced or exported cluster munitions, but it has imported and stockpiles them. Sudan sporadically used cluster bombs in Southern Kordofan province in 2012–2015, but the Monitor is unaware of any reports or allegations of cluster munition use since then. Government and military officials from Sudan have denied the country possesses and uses cluster munitions.
The Republic of Sudan has not acceded to the Convention on Cluster Munitions.
Sudan has expressed its desire to join the convention since 2010 but has not taken any steps towards accession.  It did not comment on its position on accession during the convention’s Eighth Meeting of States Parties in Geneva in September 2018.
Sudanese officials have indicated that Sudan may only join “if bordering countries follow suit.”  In 2016, an official said “the regional security situation” was “unfavorable” for joining the convention. 
Sudan participated in the Oslo Process that produced the Convention on Cluster Munitions and joined in the consensus adoption of the convention in Dublin in May 2008.  At the convention’s Signing Conference in Oslo in December 2008, Sudan expressed its intent to sign as soon as possible after completing logistical and other measures. 
Sudan has participated as an observer in almost every Meeting of States Parties of the convention, including the Eighth Meeting of States Parties in Geneva in September 2018. 
In December 2018, Sudan voted in favor of a key UN General Assembly (UNGA) resolution that calls on states outside the Convention on Cluster Munitions to “join as soon as possible.”  It has voted in favor of the annual UNGA resolution promoting the convention since it was first introduced in 2015.
Sudan is a State Party to the Mine Ban Treaty. It signed the Convention on Conventional Weapons (CCW) on 10 April 1981, but never ratified the annexed protocols.
Production, transfer, and stockpiling
There is no evidence that Sudan produced or exported cluster munitions, but it has imported them and maintains a stockpile. 
A 2016 report by a UN Panel of Experts found “clear evidence” of “current possession by the Sudanese Air Force of cluster munitions.”  A 2014 UN Panel of Experts report published photographs showing RBK-500 series cluster bombs at El Fasher airport in North Darfur state, where Sudan’s armed forces maintain a forward operating base. 
Jane’s Information Group reports that KMGU dispensers, which deploy submunitions, are also in service with the country’s air force.  Sudan also possesses Grad, Egyptian-produced Sakr, and Chinese-produced Type-81 122mm surface-to-surface rockets, but it is not known if these include versions with submunition payloads. 
There were no reports or allegations of Sudanese government forces using cluster munitions in 2018 or the first half of 2019.
Sudan has repeatedly denied using cluster munitions, but there is strong evidence that it used the weapon in Southern Kordofan province bordering South Sudan in 2012–2015.  The province has experienced fighting between Sudanese armed forces and the Sudan People’s Liberation Army North (SPLM-N) since mid-2011.
Cluster munition incidents in Southern Kordofan, 2012–2015
- According to Sudan Consortium, a civil society monitoring project, at least 23 cluster bombs were dropped in Delami, Umdorein, and Alburam (Tobo) counties in 2015. 
- Video taken after a government air attack on the town of Kauda on 27 May 2015 shows remnants of RBK-500 cluster bombs containing AO-2.5 RT submunitions. 
- Human Rights Watch (HRW) has reported evidence that the Sudanese air force used the same type of cluster bombs in attacks on Tongoli village in Delami county on 6 March 2015 and Rajeefi village in Um Durein county in late February 2015. 
- Sudanese air force used at least two RBK-500 cluster bombs in Karigiyati in June or July 2014 according to the UN Mine Action Service (UNMAS). 
- Nuba Reports alleged that Sudanese government aircraft used two cluster bombs in an attack on the village of Lado on 18 April 2013. 
- According to The Independent, government aircraft used an RBK-500 cluster bomb containing unexploded AO-2.5RT submunitions in Ongolo on 15 April 2012. 
- Chinese Type-81 dual-purpose improved conventional munitions (DPICM) were fired during a government of Sudan attack on Troji village on 29 February 2012. 
The reported use of cluster munitions in Sudan was widely condemned.  In June 2015, the UN Security Council unanimously adopted a resolution “expressing concern at evidence of possible government use of two cluster bombs near Kirigiyati in North Darfur.” 
Sudan has repeatedly denied evidence that its forces have used cluster munitions and that consistent stance is a good example of the growing norm stigmatizing such weapons.  Sudanese army officials have also denied evidence of use.  Geneva-based representatives also denied Sudan government use of cluster munitions. 
Use before 2010
Numerous independent sources have documented the presence of cluster munitions remnants that indicate Sudanese government forces sporadically used air-dropped cluster munitions in southern Sudan between 1995 and 2000, including Chilean-made PM-1 submunitions.  Landmine Action photographed a Rockeye-type cluster bomb with Chinese language external markings in Yei in October 2006. Additionally, clearance personnel in Sudan have identified a variety of submunitions, including the Spanish-manufactured HESPIN 21, United States-produced M42 DPICM and Mk-118 (Rockeye), and Soviet-manufactured PTAB-1.5. 
Since March 2015, Sudan has participated in a Saudi Arabia-led joint military operation in Yemen against Houthi forces, also known as Ansar Allah, which has used cluster munitions. Sudan has not commented on evidence that the Saudi-led coalition has used cluster munitions in Yemen, while a December 2016 statement by the coalition forces did not deny the use of cluster munitions and argued that “international law does not ban their use.” 
 In August 2010, State Minister to the Ministry of Humanitarian Affairs, Dr. Mutrif Siddiq, expressed Sudan’s intent to join the convention by its First Meeting of States Parties in November 2010. See, “Sudan Joins Enforcement of Convention on Cluster Munitions,” Sudan Vision (Khartoum), 3 August 2010. In April 2010, the Chief of Staff of the Armed Forces of Sudan, Gen. Mohamed Abd al-Qadir, stated that Sudan was ready to join the convention. See, statement by Gen. Abd al-Qadir, Armed Forces of Sudan, Sudan Mine Action Day Celebration, Khartoum, 1 April 2010.

 “International law does not ban the use 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. Neither the Kingdom of Saudi Arabia nor its Coalition partners are State Parties to the 2008 Convention, and accordingly, the Coalition’s use of cluster munitions does not violate the obligations of these States under international law.” See, “Coalition Forces supporting legitimacy in Yemen confirm that all Coalition countries aren't members to the Convention on Cluster Munitions,” Saudi Press Agency, 19 December 2016.
