A Russian strike on a hotel in the southeastern Ukrainian city of Zaporizhzhia killed one person and injured 19 on Thursday evening, regional governor Yuriy Malashko said.
Denise Brown, the U.N. humanitarian coordinator for Ukraine, said she was "appalled" by the attack, adding that the hotel was frequently used by U.N. personnel and NGO workers.
The city, located near the Russia-occupied Zaporizhzhia nuclear power plant, also faced a Russian strike Wednesday night that killed three people and caused major damage to a church, Mayor Anatoly Kurtev said. CNBC has not verified the information on the ground.
Meanwhile, the U.S. announced that it was sanctioning four people linked to the Alfa Group investment company that it described as members of Russia's financial elite.
"Wealthy Russian elites should disabuse themselves of the notion that they can operate business as usual while the Kremlin wages war against the Ukrainian people," Wally Adeyemo, deputy secretary of the Treasury, said in a statement.
"Our international coalition will continue to hold accountable those enabling the unjustified and unprovoked invasion of Ukraine."
