Late Russian opposition leader Alexei Navalny's long-time aide Leonid Volkov was assaulted with a hammer in the Lithuanian capitol Vilnius on Tuesday, former Navalny spokesperson Kira Yarmysh said.
"Volkov has just been attacked outside his house. Someone broke a car window and sprayed tear gas in his eyes, after which the attacker started hitting Leonid with a hammer," she wrote on social media website X.
She posted images showing Volkov with a bruise on his forehead, blood coming from a leg wound, and a vehicle with damage to the driver's door and window.
Lithuanian police said they had been informed a man was beaten outside his home, and were investigating.
A large part of Navalny's political vehicle, the Anti-Corruption Foundation, which includes Volkov, are residing in European Union and NATO member Lithuania after fleeing Russia.
