The governor of the eastern Donetsk region, where Moscow is focusing the brunt of its offensive, said that six civilians were killed and 15 wounded by strikes on Friday.
"There's already a governmental decision about obligatory evacuation from Donetsk region," he said in his daily address. "Please, follow evacuation. At this phase of the war, terror is a main weapon of Russia."
Zelensky warned that thousands of people, including children, were still in the battleground areas of the Donetsk region.
