Russia has issued a stark warning regarding Ukraine's potential use of Western missiles to strike deep into Russian territory, suggesting that such actions could lead to World War III. Foreign Minister Sergey Lavrov criticized the West for escalating tensions and misleadingly believing that a potential global conflict would be confined to Europe. This statement follows a significant Ukrainian attack on the Kursk region, marking the most serious foreign incursion since World War II, which has prompted Russia to refine its nuclear policy. Lavrov described Western leaders as 'playing with fire' and emphasized that they underestimate the risks involved in nuclear warfare. Ukrainian President Volodymyr Zelenskyy dismissed Russian threats as bluster, asserting that Ukraine's military capabilities are restricted by its allies. This ongoing situation raises concerns about the broader implications of the conflict and the potential for escalation involving nuclear powers.
