Ukraine needs much more modern air defense systems, President Volodymyr Zelenskyy said.

"We manage to shoot down some of the missiles and drones... But in order to guarantee the protection of our skies and reduce the capabilities of Russian terrorists to zero, we need much more modern air defense systems and missiles for such systems," Zelenskyy said.

According to him, Monday's airstrikes have led to new power outages in Ukraine, "but it is being fixed."

"Restoration work is ongoing," he assured, urging Ukrainians to "consciously consume" electricity during the peak hours of grid overload.

"This will enable the whole country to go through this period more stably," Zelenskyy added.
