Russia's defense ministry said on Tuesday its forces had destroyed ammunition depots in Ukraine's southern Odesa region that were storing weapons supplied to Kyiv by the United States and European countries.

It did not say how many depots it had destroyed or what weapons were being stored there.

Deputy Chairman of the Russian Security Council Dmitry Medvedev said on Tuesday via Telegram that he did not rule out the possibility of creating a special mechanism to investigate the arms delivery from the U.S. to Ukraine.
