Russia launched a large-scale missile and drone attack on Ukraine overnight, targeting regions across the country, Ukrainian officials said on Saturday.

“All night Ukraine was under a massive attack by Russia,” Ukrainian President Volodymyr Zelenskyy said on social media. “The enemy aimed at our infrastructure, residential areas and civilian enterprises,” he said.

Moscow launched 619 drones and missiles at Ukraine, according to the Ukrainian air force, including 579 strike drones, eight ballistic missiles and 32 cruise missiles. Ukrainian air defense was able to shoot down 583 aerial targets, they added.

The air attack struck multiple regions in Ukraine, including Dnipro, Mykolaiv, Chernihiv, Zaporizhzhia, Poltava, Kyiv, Odesa, Sumy and Kharkiv, Zelenskyy said. Three people were killed and dozens more injured in the strikes, he said.

“Every such strike is not a military necessity but a deliberate strategy by Russia to terrorize civilians and destroy our infrastructure,” the Ukrainian president said. “That is why a strong international response is needed.”

The attack comes a day after three Russian fighter jets violated Estonian airspace, an incursion which has been condemned by Estonia and EU officials. Moscow denied that its jets violated Estonia airspace.

In the early hours of Saturday, Poland said it deployed aircraft in its airspace due to Russia’s ongoing strikes on Ukraine close to the Polish border. “The measures taken aim to ensure safety in areas bordering the threatened regions,” said the Polish armed forces. It later confirmed it had terminated the operation.
