"Russia has ratcheted up tensions with the West amid its ongoing war against Ukraine, with President Vladimir Putin saying Moscow will deploy "tactical nuclear weapons" in Belarus. The Russian leader said 10 fighter jets capable of carrying tactical nuclear weapons — generally a reference to smaller weapons used for limited battlefield attacks, rather than larger, long-range "strategic" nuclear weapons — were already deployed in Belarus. Putin said Russia would also position nuclear-armed Iskander hypersonic missiles, with a range of around 300 miles, in Belarus."
