Ukrainian President Volodymyr Zelensky had brushed aside Western criticism of Kyiv using a Turkish-made drone in its conflict with pro-Moscow rebels, saying his country was "defending its territory."

President Vladimir Putin had earlier told his defence chiefs to work on further developing Russia's arsenal of drones, especially through artificial intelligence.
