Russian forces captured Loskutivka, Myrna Dolyna, Rai-Oleksandrivka, and Pidlisne all on the 22nd of June.[100][101] On 23 June, Russian forces cut off and surrounded the towns of Hirske and Zolote, which they claimed to have fully captured by next day.[102][103] In addition, Russia made a push to fully secure the Azot chemical plant in Sievierodonetsk, which by 14 June had become the last refuge for Ukrainian soldiers in the city.[104] From the north, Russian troops were less successful, attempting to make breakthroughs near Mykolaivka and Bohorodychne, in an attempt to advance on the Donetsk city of Sloviansk.[105][106] Nonetheless, the Russian advance ground on, with Russia's breakthrough in the south putting pressure on the few remaining Ukrainian defenders of Luhansk Oblast to withdraw to defensive lines near the border with Donetsk Oblast.[107]
