Russian forces have captured two villages in Ukraine, one in Kharkiv region in the northeast and one in eastern Donetsk region, the Russian Defence Ministry says.
Donetsk region is where Moscow is concentrating most of its efforts to seize two cities.
Russian forces, making steady progress across Donetsk region, are moving on the towns of Pokrovsk, a logistics centre and site of an important coking colliery, and appear to be closing in on Kurakhove, farther south.
A defence ministry statement on Sunday said troops had taken control of Lozova, near the town of Kupiansk, in an area north of Donetsk region also under Russian pressure in recent weeks. The village of Sontsivka, north of Kurakhove, was also captured.
The ministry on Saturday announced the capture of another village near Kurakhove, Kostiantynopolske.
The Ukraine military's general staff made no mention of those villages falling into Russian hands, but said Sontsivka was in a sector subject to 26 Russian attacks in the past 24 hours. The general staff also reported heavy fighting near Pokrovsk, with 34 Russian attempts to pierce defences.
The popular Ukrainian military blog DeepState said Sontsivka was under Russian control.
Russian reports have described intensified pressure on Kurakhove.
The Moscow-appointed governor of areas of Donetsk region occupied by Russian forces, Denis Pushilin, said on Telegram that Russian troops now controlled the town centre. He also said troops were advancing on Pokrovsk from the south.
Russian troops have been moving through eastern Ukraine in the past two months at the fastest rate since Russia launched its full-scale invasion of Ukraine in February 2022.
The Ukrainian military said on Friday its forces had pulled back from the area around two villages - one near Pokrovsk, the other near Kurakhove - to avoid being encircled by advancing Russian troops.
