Russian President Vladimir Putin is determined to conquer parts of Ukraine and shows no restraint in his brutality, but it is still important to keep contacts open in case a moment arrives to end the war, German Chancellor Olaf Scholz said. All non-critical infrastructure in Ukraine's southern port city of Odesa was without power on Saturday after Russia used drones to hit energy facilities, local officials said, with much of the surrounding region also affected. Russian forces have shelled the entire front line in the Donetsk region in eastern Ukraine, Ukrainian officials said on Friday.
