(Reuters) -U.S. national security adviser Jake Sullivan spoke on Wednesday with Nikolay Patrushev, secretary of Russia's Security Council, warning him of the consequences "of any possible Russian decision to use chemical or biological weapons in Ukraine".

A White House statement after the call, the first high-level contact publicly disclosed between the two countries since Russia's invasion of Ukraine, did not specify what those consequences would be.
