Did Vladimir Putin send a body double to Ukraine?
Anton Gerashchenko, a Kyiv official, posted pictures of Putin's chin, comparing them to photos taken during the visit, and questioned if they belonged to the same man.
The images of Putin's chin show differences from his address to the Federal Assembly in Moscow, and his visit to Sevastopol in Crimea.
There have been claims that Putin uses body doubles on some trips outside Moscow, or when there are lots of people around.
Some Twitter users also commented that looking at the ears might be a good way to tell whether or not a body double is being used.
