Vladimir Putin saluted the "heroes" fighting in Ukraine and the rearmament of Russia on the occasion of the day celebrating the Russian armed forces. The United States, for its part, promised to announce new sanctions against Moscow on Friday.

Weakened by the blocking of American aid, the failure of its summer counter-offensive and a growing lack of ammunition, the Ukrainian army is facing an "extremely difficult" situation, according to the president's own admission. American President Joe Biden, for his part, met on Thursday the daughter and widow of Alexeï Navalny.
