Regarding France, they are worried as well:
France’s foreign ministry on Monday advised French nationals to avoid non-essential travel to Ukraine as tensions soared over the Russian military buildup, prompting NATO allies to put forces on standby and send ships and fighter jets to bolster Europe's eastern defences.
A French foreign ministry statement “strongly recommended” that nationals “postpone any travel to Ukraine that is not essential or urgent".
Due to the Russian military buildup on the border with its neighbour, France cautioned its nationals to “avoid border areas in the north and the east of the country", the statement said.
