Ukraine can’t stop Vladimir Putin’s re-election as Russian President on Sunday, but that doesn’t mean it can’t shatter the perfect image of his sacred day – by bringing the war once again to Russian soil. Throughout the week, Ukrainian drones have been striking oil refineries and energy facilities deep inside Russian territory, while anti-Kremlin Russian militias fighting on Ukraine’s side have crossed the border on tanks and started a fight with Russian forces.

This incursion into Russian territory wasn’t unprecedented: last spring, exiled Russians fighting on Ukraine’s side infiltrated several Russian towns in the Belgorod region, fought for several days, and then withdrew. The dire state of Russia’s border defences hasn’t improved since then: on Tuesday, some one hundred fighters of the Freedom of Russia Legion, the Siberian Battalion and the Russian Volunteer Corps entered the Belgorod and Kursk regions. Since then, they claim to have captured one village and reported fighting in four others, also publishing videos of their skirmishes. Russian officials have denied the fall of Tyotkino in the Kursk region but confirmed ongoing battles.

In addition to keeping a part of the Russian army from moving into Ukraine, Oleksii Baranovskyi, a fighter with the Freedom of Russia Legion, said the attacks were the fighters’ ‘voting method’: ‘We, as caring citizens of Russia, have thus decided our political will, our attitude towards these elections, and the regime of Vladimir Putin.’ Soldiers have urged Russians via social media to ignore the presidential elections, calling the ballots and polling stations ‘fiction’. They also asked civilians from the Belgorod and Kursk regions to stay in the basements or evacuate until the regions are ‘completely liberated from the Putin regime’s troops’.

In public, Putin hasn’t appeared too concerned by the cross-border invasion: after all, why worry about a few more dead Russian soldiers? ‘I have no doubt that the main purpose is to, if not disrupt the presidential elections in Russia, then at least somehow interfere with the normal process of expressing the will of citizens,’ he said this week in an interview with Russian state media.
