WASHINGTON (Reuters) - The United Nations Security Council will convene on Friday at Russia's request, diplomats said, to discuss Moscow's claims, presented without evidence, of U.S. "biological activities" in Ukraine, a move Washington described as gaslighting.

The meeting is expected to be in the morning.
