Ukraine's military says it is 'welcoming' French trainers in Ukraine, in new remarks which strongly suggest that for the first time France is deploying its troops to Ukraine soil. This marks the beginning of major 'boots on the ground' escalation in a formal, public capacity by a NATO state.

"Ukraine's top commander said on Monday he had signed paperwork allowing French military instructors to visit Ukrainian training centers soon," Reuters reported Monday, referencing head of the armed forces Col. Gen. Oleksandr Syrskyi.

"I am pleased to welcome France's initiative to send instructors to Ukraine to train Ukrainian servicemen," Syrskyi said following video link talks with French defense minister Sebastien Lecornu.
