Russia fired a wave of drones and missiles at Ukraine overnight, killing four people, while Ukrainian strikes on Russia and Russian-occupied areas of Ukraine killed five, officials said Sunday.
The strikes came a day before Ukraine's allies were set to meet in Paris for talks on pressuring Russia to end its more than four-year war.
U.S.-led diplomatic efforts to end the fighting have stalled in recent months, as Washington has shifted focus to its war with Iran.
Moscow has meanwhile escalated its campaign of ballistic missile strikes on Ukraine, killing dozens of people including in the capital Kyiv since July.
Three people were killed in Russian attacks on Ukraine's central Dnipropetrovsk region overnight, including two in a strike on an “industrial enterprise” in the city of Kryvyi Rih, regional officials said.
