A former Ukrainian nationalist MP has died after being shot on the street in the western city of Lviv.
Iryna Farion caused controversy in 2023 by suggesting that “true patriots” of Ukraine should not speak Russian under any circumstances.
The 60-year-old linguistic professor's killing on Friday is being investigated and police say it may have been a targeted attack.
Her attacker has not been identified. Police say a power outage affected CCTV in the area.
Lviv Regional Governor Maksym Kozytskyi said on Telegram that Ms Farion died in hospital after the shooting.
Interior Minister Ihor Klymenko said “this was not a spontaneous killing” and police were looking for a motive.
"We already have several versions. The main ones, I can say, are [linked to Farion's] social and political activities and personal dislike," he said in a statement via the Telegram message service.
"We do not rule out that the murder has a commissioned character," he added.
President Volodymyr Zelensky said on Telegram that “any violence must be condemned and whoever is guilty of this attack must bear full responsibility".
The hardline nationalist Svoboda (Freedom) political party Ms Farion was a member of blamed Russia for the killing.
"Moscow shoots in the temple for the Ukrainian language," it said in a statement.
In 2023, Ms Farion said that true patriots of Ukraine should not speak Russian in any settings, including on the front lines, as it is the language of the aggressor country.
She described Russian as "the language of the enemy, who kills, discriminates, insults and rapes me", and added: "How crazy should you be to fight in the Ukrainian army and speak Russian?"
Her words provoked a strong reaction in Ukraine at the time, with people accusing her of inciting hatred based on linguistic preferences.
She was dismissed from a university in western Ukraine and was investigated by the Security Service of Ukraine (SBU).
In May, the Lviv Court of Appeal reportedly issued a ruling reinstating her to the position.
