According to the BBC, a Russian drone struck the headquarters of Ukraine's Security Service (SBU) in central Kyiv on Friday afternoon, hitting a room used by security chief Oleksandr Poklad. President Volodymyr Zelensky said he had spoken to Poklad and ordered an appropriate response, while Foreign Minister Andriy Sybiha called the attack a major escalation. Kyiv Mayor Vitali Klitschko said five people were hurt. The Russian defense ministry also said it struck a cargo vessel in the Ukrainian port of Chornomorsk and a tanker near Odesa. The attack came as US mediators Steve Witkoff and Jared Kushner were due to visit Russia and Ukraine this weekend for talks on ending the war.
