Russian opposition activist Leonid Volkov, who was the former chief of staff of the late Russian opposition leader Alexey Navalny, was attacked outside his home in the Lithuanian capital Vilnius on Tuesday, according to Navalny's spokeswoman Kira Yarmysh.
"Leonid Volkov has just been attacked outside his home. Someone broke the car window and threw tear gas into his eyes, and then the attacker hit Leonid with a hammer," Yarmysh said in a social media post.
Ivan Zhdanov, director of Navalny's Anti-Corruption Foundation, said Volkov was attacked "near the house" and "they hit his legs with a hammer as well as hit his arms."
Images shared by Zhdanov showed Volkov with a swollen face and a bleeding leg. Broken glass and blood are seen next to a car in another photo. Volkov has been taken to hospital, Zhdanov said in a social media post.
Lithuanian authorities are investigating Tuesday's attack, the country's Foreign Minister Gabrielius Landsbergis said in a post on X. "The perpetrators will have to answer for their crime," Landsbergis said, describing the attack as "shocking."

The attack comes days before Russia's presidential election, seen as a constitutional exercise where President Vladimir Putin is certain to win a fifth term.
Volkov, who had served as chairman of Navalny's Anti-Corruption Foundation until 2023, dismissed the February election as a "circus" and said on social media that it was meant to signal overwhelming mass support. of Putin.
"You have to understand what the March 'elections' mean for Putin. They are a propaganda effort to spread hopelessness" among the electorate, Volkov said.
The opposition figure has been living outside Russia for several years for security reasons. She faces numerous politically motivated charges in Russia.
Navalny, who was Russia's most prominent anti-Putin voice, died last month in a Russian prison, prompting condemnation from world leaders and accusations from his aides that he had been murdered. The Kremlin has denied any involvement in his death.
Navalny's team and many other Russian activists have fled the country in recent years as Moscow's increasingly repressive regime cracked down on any opposition. In 2021, a Moscow court said the Anti-Corruption Foundation was an "extremist" group in a ruling that was widely condemned by the international community.
