Ukrainian authorities announced, on Friday, 222 people, including 60 citizens and four children, had been killed in Kyiv since Russia invaded the country.

"A further 889 people have been wounded, including 241 civilians," the Kyiv city administration said in a statement.

In the same vein, nearly 7,000 Russian troops have been killed so far, according to sources.

The figure, first reported by The New York Times, is expected to raise. Some estimates place the number of Russian troops killed in Ukraine at about 3,000, whereas others suggest more than 10,000 have been killed.

"It becomes more evident every day that Putin gravely miscalculated," a senior NATO intelligence official told reporters at NATO headquarters, speaking on the condition of anonymity to disclose sensitive assessments.

"Russia continues to face difficulties replacing its combat losses, and increasingly seeks to leverage irregular forces, including Russian private military corporations and Syrian fighters."

A senior NATO military official echoed that assessment, saying that "we can assess that more private military companies will be engaging" in the conflict soon. But in general, he said, the losses have had "a bad effect on the morale of the troops."
