Russian President Putin emphasized that European forces on the territory of Ukraine are unacceptable.
"From the beginning, we have said that the presence of any foreign troops on the territory of Ukraine is completely unacceptable to us. Any kind of foreign soldiers on Ukrainian soil will be unacceptable - completely unacceptable - to you.
Because we believe it threatens the security of the Russian Federation. And in principle everyone agreed with it. At least that was the case during the negotiations in Istanbul. And so far no one has really objected to it. ".
