President Joe Biden’s top national security aide warned his Russian counterpart Wednesday against using chemical or biological weapons in Ukraine, and urged the Kremlin to stop attacking urban areas in its invasion.

U.S. National Security Adviser Jake Sullivan told General Nikolai Patrushev, secretary of the Russian Security Council, that there would be unspecified “consequences and implications of any possible Russian decision to use chemical or biological weapons in Ukraine,” National Security Council spokeswoman Emily Horne said in a statement.
