Russia continued its nightly bombardment of Ukrainian cities overnight into Tuesday, after President Donald Trump said the U.S. would send military equipment to Kyiv.

Trump’s threats of secondary tariffs are “never going to go anywhere” as long as he is unwilling to impose costs on Moscow directly, Keir Giles, a senior fellow at the London-based Chatham House think tank, told NBC News Monday.

President Donald Trump on July 14 announced the U.S. would impose "severe tariffs" on Russia unless Moscow agrees to a deal to end the war in Ukraine within 50 days, but experts who spoke to the Kyiv Independent say the plan is deeply flawed.
