Human Rights Watch said in a report that Syrian activists posted at least 18 videos on Oct. 9-12 showing remnants of the bombs in or near several towns, which included the central city of Homs, the northern cities of Idlib and Aleppo, the countryside in Latakia, and the Eastern Ghouta district near the capital Damascus. Many were on a north-south highway that has been the scene of fighting in recent days.
Cluster bombs are of particular concern because they scatter small bomblets over a wide area. Many bomblets do not immediately explode, posing a threat to civilians for long afterward.
Human Rights Watch said the munitions in the video were Soviet-made. Before its collapse, the Soviet Union was a major arms supplier to Syria.
