President Volodymyr Zelensky says Russia has launched more than 30 drone attacks on Ukraine in just two days.
He added that in total, Moscow had also carried out some 4,500 missile strikes and over 8,000 air raids.
Speaking from Kyiv and standing beside what appeared to be a downed Iranian Shahed drone, Mr Zelensky pledged to clip the wings of Moscow’s air power.
Western officials believe Iran has supplied a large number of drones to Russia, but Moscow and Tehran deny it.
This comes as US Secretary of State Antony Blinken called Russia’s aggressive use of drones appalling.
