In Kyiv, Ukrainian President Volodymyr Zelensky warned in a televised address on Thursday that much of Ukraine will face extended blackouts after Russia launched a series of attacks on energy infrastructure. Zelensky spoke from a darkened street next to the wreckage of what he said was an Iranian-made drone used in recent assaults. He said Ukraine had shot down 300 of the drones and that Russia has launched more than 8,000 airstrikes and 4,500 missiles since it invaded in February.
