UNITED NATIONS - U.N. Secretary-General Antonio Guterres is "deeply shocked" by Russia's most widespread air strikes since the start of the Ukraine war on Monday, a U.N. spokesman said.

"This constitutes another unacceptable escalation of the war and, as always, civilians are paying the highest price," U.N. spokesman Stephane Dujarric said in a statement.
