Institute for the Study of War: Russian proxies in Mariupol struggle to establish administrative control of the city.

The U.S. think tank said temporarily-occupying Russian and Russian proxy authorities in Mariupol reportedly struggled to establish administrative control of the city on May 19. Aide to Mariupol Mayor Petro Andriushchenko said pro-Russian collaborators in Mariupol are guided by Russia’s Federal Security Service instead of the leadership of Russian-occupied Donbas.
