Former President Jimmy Carter, who was president during the Cold War, while the Soviet Union was still intact, said Russia's "unprovoked attack on Ukraine using military and cyber weapons violates international law and the fundamental human rights of the Ukrainian people."

US official: Russian forces advance but not as quickly as anticipated
Russian forces continue to invade Ukraine along three routes, including from the north toward Kyiv, although a senior U.S. Defense Department official said Russian momentum toward Kyiv has slowed in the last 24 hours.

The U.S. official declined to say how many Russian troops were on the ground in Ukraine now, but estimated it was about one third of the combat force that Russia had massed before the attack. Russian President Vladimir Putin had deployed more than 150,000 troops on Ukraine’s border prior to the invasion.

The official, speaking on condition of anonymity to discuss intelligence findings, told reporters Friday the U.S. had information suggesting that Moscow had expected a faster advance on Ukraine's capital. The official declined to say how the Pentagon had made that assessment, but Russia has not yet captured any major population centers.

Russia has failed to dominate Ukrainian air space, the official said. Ukraine continues to fly warplanes that are attacking Russian forces. Ukraine also retains missiles for air defense.

In southern Ukraine, the Russians have made an amphibious attack, landing thousands of troops, the official said.

Elsewhere in the south, a battle is being fought for the Kakhovka hyrdo-electric plant that provides energy to Crimea and southern Ukraine. Russia has launched cyberattacks there, the official said.
