Russian prosecutors have requested a 25-year prison sentence for Kremlin critic Vladimir Kara-Murza, in a case widely condemned by international human rights organizations. Kara-Murza has been a vocal opponent of President Vladimir Putin and has been arrested multiple times for his activism against the government. The sentencing request comes amid escalating tensions between Russia and Ukraine, with Chinese President Xi Jinping expressing willingness to speak to Ukrainian President Volodymyr Zelenskyy.
