Ukrainian President Volodymyr Zelensky has accused Russia of attempting to exploit the war in the Middle East to cause "even greater destruction" in his country.

He said Ukraine needed air-defence systems regardless of what was happening elsewhere. The US-Israeli war with Iran has led to many air-defence missiles being expended fending off retaliatory attacks.

Zelensky's comments came after Russia launched another massive aerial bombardment overnight into Saturday in which at least five people were killed.

About 500 drones and missiles were launched during the latest wave of Russian strikes, he said. Though most were intercepted, they caused casualties and damage across the country, he added.

"The main target for the Russians was the energy infrastructure of the Kyiv region, but unfortunately there were also direct hits on and damage to ordinary residential buildings, schools, and civilian businesses," Zelensky stated.
