Ukrainian president Volodymyr Zelensky has sacked two senior members of the Ukrainian national security service, labelling them as traitors and antiheroes.
In an early morning video address on Friday, as the war in Ukraine entered day 37, Mr Zelensky said he had fired Naumov Andriy Olehovych, the chief of the main department of the Security Service of Ukraine (SBU), and Kryvoruchko Serhiy Oleksandrovych, the head of the SBU in Kherson, the first major city that fell to the Russians.
