The Eiffel Tower was lit in the colours of Ukraine's flag on Thursday in a mark of support for Kyiv on the eve of the first anniversary of Russia's invasion.
The tower, one of the world's most visited landmarks, was swathed in blue and yellow light shortly after sundown in the French capital.
"Glory to Ukraine!" tweeted Paris mayor Anne Hidalgo in Ukrainian.
Hidalgo had asked for the show of support, which comes as France, like other western countries, is boosting arms deliveries to Kyiv.
The French defence ministry said last week that the first batch of AMX-10 armoured vehicles President Emmanuel Macron promised would be delivered within days.
