Russia has said that German Leopard 2 tanks are equipped with sub-calibre armour-piercing shells with uranium cores, and Moscow will consider their use in Ukraine against Russians as the use of "dirty bombs".

Quote from Gavrilov: "We warn the Western sponsors of the Kyiv military machine against encouraging nuclear provocations and blackmail."
"We are aware that the Leopard 2 tank, as well as the Bradley and Marder infantry fighting vehicles, are armed with sub-calibre armour-piercing shells with uranium cores, the use of which leads to contamination of the area, as it happened in Yugoslavia and Iraq.
If Kyiv is supplied with such shells for NATO heavy military equipment, we will consider it to be the use of dirty nuclear bombs against Russia with all the ensuing consequences."
