The hasty announcement of these elections was accompanied by that, Wednesday by Vladimir Putin, of the immediate mobilization of at least 300,000 reservists.

The Russian president also threatened to use all of Russia's arsenal, which includes nuclear weapons.

This mobilization continued in Russia, the Kremlin seeking the parade with the advances of the Ukrainian army which, strong of the deliveries of Western weapons, claimed new territorial progress Friday.

On this subject, Mr Zelensky called on all Ukrainians who find themselves in the territories occupied by the Russians to "go into hiding to escape Russian mobilization" and, if they cannot escape it, to "sabotage any activity of the enemy".

The announcement of the mobilization pushes many Russians to leave the country

If television broadcast almost no images of the mobilization, several videos on social networks showed men with closed faces getting on buses after kissing their loved ones, some in tears.

Reached by AFP, Konstantin, 29, said he received his summons at his parents' home.

"I'm still in shock," he said.

"I'm not going to hide but I'm not jumping for joy either".

Others were given a summons after being arrested during demonstrations against the mobilization on Wednesday.

"I expected the usual (procedures): the arrest, the police station, the court. But being told: + Tomorrow you are going to war + (...) that was a surprise", told AFP Mikhail Suetin, 29, who refused to sign the document.

The announcement of the mobilization also prompted many Russians to leave the country, causing an influx at the borders, without it being possible to quantify the extent of the phenomenon.

Finland has decided to take measures to "significantly" limit the entry of Russian citizens on its soil, while the Baltic countries and Poland have already been drastically curbing entry for weeks.
