Over the past week, Russia has been attempting to establish a 15-kilometre "buffer zone" in Kharkiv oblast, while the Ukrainian Armed Forces managed to launch a partial counter-offensive and recapture several positions occupied by the Russians near Kupyansk. Along with frontline developments, this episode focuses on the main achievements of the Security Agreement with the UK, delivered by “the representative of the oldest parliament to the most courageous parliament.” This is our weekly roundup of key events and trends in and around Ukraine. Volodymyr Yermolenko, the chief editor of UkraineWorld, is joined by Anastasiia Herasymchuk and Dariia Synhaievska, analyst and journalist at UkraineWorld, to discuss key events and trends in and around Ukraine over the past week.
