This is reported by Newsweek, citing a US intelligence source.

"The President of Ukraine has been warned that Russia is likely to launch an 'invasion' within 48 hours," the statement said.

In addition, it is noted that on the morning of February 23, "Russia violated the airspace of Ukraine, making a short flight over Ukraine, possibly with a reconnaissance aircraft."

Earlier, French Finance Minister Bruno Le Maire said that the word “invasion” used by US President Joe Biden is not suitable to describe the ongoing events in Ukraine.

British Foreign Secretary Liz Truss also noted that there is no unequivocal evidence that Russia is “sending troops to the Donbass” yet.
