Demonstrations by pro-Russian activists began to spread across Luhansk Oblast towards the end of April. The municipal administration building in Pervomaisk was overrun on 29 April 2014, and the Luhansk People's Republic (LPR) flag was raised over it. Oleksandr Turchynov, then acting president of Ukraine, admitted the next day that government forces were unable to stabilise the situation in Donetsk and Luhansk oblasts. On the same day, activists seized control of the Alchevsk municipal administration building. In Krasnyi Luch, the municipal council conceded to demands by activists to support the 11 May 2014 referendum, and followed by raising the Russian flag over the building.
