Russia launched its largest barrage of drones and missiles in a month across Ukraine, killing at least three people, Ukrainian President Volodymyr Zelensky said Saturday, as a Kyiv delegation heads to the United States for fresh peace talks.

The attack came as U.S. officials were expected to hold peace talks with Ukrainian and Russian officials in the coming days.

In Russia, a major oil terminal near the port of Novorossiysk stopped operations Saturday after a strike by unmanned boats damaged one of its three mooring points, according to a statement from the Caspian Pipeline Consortium, or CPC, which owns the terminal.

Russian drone and missile attacks in and around Kyiv killed at least three people as the country’s representatives traveled to the U.S. to work on a renewed push to end the war.

"If this is true, then we have a major problem, Houston," wrote Estonian lawmaker Marko Mihkelson, in response to the report.

A Russian drone and missile blitz left more than 600,000 people in Kyiv without power on Saturday as the embattled capital city braced for a freezing winter. Three people were killed and more than 30 injured in the overnight air assault,
