Ukraine's president says Russia is planning a protracted campaign of drone attacks in a bid to demoralize Ukraine, APA reports citing BBC.
Volodymyr Zelensky said he had received intelligence reports suggesting that Moscow would launch the attacks using Iranian-made Shahed drones.
It comes after Ukraine carried out a strike that it said killed hundreds of Russian soldiers in the Donbas region.
In an extremely rare admission of battlefield losses, Russia said the attack killed 63 of its troops.
Speaking from Kyiv in his nightly address, Mr. Zelensky said Russia planned to "exhaust" Ukraine with a prolonged wave of drone attacks.
"We must ensure - and we will do everything for this - that this goal of terrorists fails like all the others," he said. "Now is the time when everyone involved in the protection of the sky should be especially attentive."
Russian drone strikes on Ukraine appear to have increased in recent days, with Moscow launching attacks on cities and power stations across the country over the past three nights.
