That's provided the West's NATO allies time to meet in Brussels on how to make Russia's offensive as painful as possible for President Vladimir Putin — without triggering a nuclear war.On that, Russia issued an unsubtle warning, answered Thursday by France.
Senior Russian official Dmitry Rogozin said in televised remarks that "within minutes at any distance," the country’s nuclear arsenal would help deter the West from intervening in Ukraine.
He then named several types of nuclear weapons Moscow is considering using in the conflict.Meanwhile, Russia's stock market reopened for limited trading Thursday.RELATED: Zelenskyy pleads for aid as Biden, Western allies begin summits on Russian warHere are some key things to know about the Russia-Ukraine war:Zelenskyy is calling on people worldwide to gather in public Thursday to show support for his embattled country as he prepared to address U.S.
