Pokrovsk and seek to pierce the Ukrainian defensive front lines. Russian forces, which control about a fifth of Ukraine since invading in February 2022, are advancing in eastern Ukraine in an attempt to take the whole of the Donbas.
Russia's defence ministry said its forces had taken the town of Novohrodivka, which lies 12 km from Pokrovsk, an important rail and road hub for Ukrainian forces in the area. The town had a population of 14,000 before the war.
Yuri Podolyaka, an influential Ukrainian-born, pro-Russian military blogger, published maps showing Russian forces attacking beyond Novohrodivka in at least two places less than 7 km (4 miles) from Pokrovsk.
The General Staff of the Ukrainian military, in a late afternoon report, described the situation as «tense» throughout the Pokrovsk sector and said «fierce battles» gripped areas around several towns, including Novohrodivka.
