Cluster munitions provided by the United States and other countries are currently in Ukraine, Joint Staff Director for Operations Lt. Gen. Douglas A. Sims said on Thursday.
"There are cluster munitions in Ukraine at this time," Sims said during a press briefing.
There were cluster munitions in Ukraine provided by third-party countries prior to the US’ delivery of the weapons, Sims added.
Earlier, Anatoly Antonov, the Russian ambassador to the US, stated that Washington's decision to deliver cluster munitions to Ukraine was a sign of desperation and that it disregarded the concerns of its allies as the US "ignored the negative voice of its [NATO] allies regarding the dangerous use of indiscriminate cluster munitions".
Among NATO-members, Canada and Britain have expressed their concerns over the Washington's move and spoke against such a decision, since both countries are parties to the convention on the prohibition of the use of cluster munitions.
