Russia's Vladimir Putin issues new nuclear warnings to West over Ukraine

MOSCOW (Reuters) — President Vladimir Putin on Tuesday delivered a warning to the West over Ukraine by suspending a landmark nuclear arms control treaty, announcing that new strategic systems had been put on combat duty, and threatening to resume nuclear tests.

Nearly a year after ordering an invasion that has triggered the biggest confrontation with the West in six decades, Putin said Russia would achieve its aims and accused the West of trying to destroy it.
