Syrian government use of cluster munitions has been widespread and is ongoing. Cluster munitions are also used extensively in the Syrian-Russian joint operations. Between July 2012 and June 2018, over 600 cluster munition attacks were recorded by the Cluster Munition Monitor.

Between July 2017 and June 2018, at least 36 cluster munition attacks were documented in Syria, and numerous additional possible instances of use could not be fully confirmed.

Evidence recorded by local activists, journalists, first responders, medical personnel, and others points to at least 238 separate attacks using cluster munitions in Syria between August 2016 and July 2017.

In January and February 2016, the Syrian-Russian joint military operation included the use of cluster bombs in at least 14 attacks that killed or injured dozens of civilians. In June and July 2016, at least 47 cluster bomb attacks were documented.

Between September and December 2015, cluster munitions were used on at least 20 occasions. At least 35 civilians, including five women and 17 children were killed and dozens injured. The cluster munitions were manufactured in the former Soviet Union or Russia.

Between July 2012 and July 2014, Syrian forces used at least 249 cluster munitions in 10 of Syria’s 14 governorates. The actual number is most probably much higher as not all remnants have been recorded. At least seven types of cluster munitions, including air-dropped bombs, dispensers fixed to aircraft, and ground-launched rockets, and at least nine types of explosive submunitions were used.

In July and August 2014, the armed group Islamic State used at least one type of rocket-fired cluster munition and submunition.

From 2012 to the end of 2017, at least 3,076 cluster munition casualties (people inured or killed) were confirmed in Syria. There were increasing hazards for people collecting data as the extreme difficulties faced by those working inside Syria continued to intensify.

Cluster Munition Coalition call

  • All parties to the Syria conflict should renounce use of cluster munitions, an internationally banned weapon.
  • Cluster munition stockpiles should be declared and destroyed.
  • Cluster munition remnants must be cleared and destroyed as soon as it is safe to do so and international support should be given to enable clearance.
  • Through risk education, warnings must be given to communities about the danger posed by unexploded bomblets.
  • The victims of cluster munitions and other explosive weapons must be supported, including civilian refugees displaced by the use of these weapons.
  • Governments worldwide should continue to condemn the use of cluster munitions in Syria, and call for Syria and all states to join the Convention on Cluster Munitions.

The leadership of the Convention on Cluster Munitions and states worldwide have spoken out against the use of this banned weapon.

"We call upon the Syrian regime to immediately stop the further use of cluster munitions, and to comply strictly with all its obligations under international humanitarian law. [These] continuous violations of international humanitarian law will lead to a situation in which it will be fully held accountable for these horrific acts against its own population," said the President of the 6th Meeting of States Parties to the Convention in February 2016.

To-date, a total of 162 countries have condemned the use of cluster munitions in the context of ongoing use in Syria, most through four UN General Assembly resolutions. At least 37 states have issued national statements expressing concern.

The Syrian military has denied possessing or using cluster munitions, and the government usually does not respond to or comment on its use of cluster munitions. Russia has denied using cluster munitions in Syria.

A selection of recorded instances of use and testimonies of cluster bomb attacks in Syria

“Suddenly the jet came and dropped its bombs. The bombs fell from above, one after another, small bombs spread out in the sky. They were exploding everywhere, like a volcano erupting, on and on. Shrapnel hit me in my behind and back. I was taken to the hospital which was full of wounded people, many in critical condition.”
Sheik Sa`eed Neighborhood, Aleppo City, Syria

“There were so many injured, they had horrible cuts and pieces of flesh missing. Little children were screaming in so much pain; it was heart breaking, and the medics in the field hospital didn’t know who to attend to first.”
Southern district of Sarmin, a small town in the Idlib governorate, Syria
