The Italian defence ministry said Lieutenant Colonel Claudio Castiglia died in Italy of natural causes, after the Russian embassy in South Africa reposted reports that Castiglia had been found dead in Ukraine.

"The Italian Defence firmly denies this macabre lie published on the "X" account of the Russian Embassy in South Africa and warns the sowers of hatred against continuing to spread this horrendous fake news," the statement said.

"Is this how psychological warfare is fought, renewing the grief of the family of Lieutenant Colonel Claudio Castiglia?," the Italian statement said.

Last month, the Italian cabinet passed a decree that allows it to supply Kyiv with military equipment until the end of 2024, to support its war effort against the Russian invasion and protect its civilians.
