An advanced type of Russian-made cluster munition was used in an airstrike near the Syrian city of Aleppo on Oct. 4, Human Rights Watch said on Sunday.
Using the weapon “raises grave concerns that Russia is either using cluster munitions in Syria or providing the Syrian air force with new types of cluster munitions to use,” the group said in a statement.
Human Rights Watch said that photographs and videos also suggest the “renewed use of air-dropped cluster munitions as well as ground-fired Russian-made cluster munition rockets as part of the joint Russian-Syrian offensive in northern Syria.”
Russian President Vladimir Putin has ordered a bombing campaign in Syria against Islamic State militants. The U.S. as well as Syrian opposition groups say the attacks are targeting rebels fighting President Bashar al-Assad, an ally of Moscow.
