Depleted uranium ammo fuels nuclear tensions in Ukraine.

The US is reportedly set to approve the provision of depleted-uranium tank shells to Ukraine, capable of penetrating Russian tank armor. The decision was previously delayed due to concerns over environmental and health impacts. Depleted uranium is a by-product of the nuclear enrichment process and is used because of its density. The UK has already provided Ukraine with the ammunition, which was denounced by Russian President Vladimir Putin. US officials believe it is vital for Ukraine to make decisive gains in its counteroffensive while bipartisan support for the country remains high.
