Artillery strikes have intensified near the eastern Ukrainian cities of Kupyansk and Lyman in recent weeks, a spokesperson for Ukraine's military said Sunday.
"This area has been leading in the number of artillery strikes for several weeks now," said Serhii Cherevatyi, who represents the Eastern Grouping of the Ukrainian Armed Forces.
The area has seen 370 artillery and Multiple Launch Rocket System strikes over the last day alone, Cherevatyi said on national television.
The spokesperson said the attacks differ from those in the besieged city of Bakhmut, because Wagner mercenary forces have been conducting those assaults, whereas Kupyansk and Lyman are being targeted by regular Russian troops.
Russian forces in the Kupyansk-Lyman area are mostly reinforced by conscripted Russian troops, Cherevatyi said.
"They are engaged in more 'classical' combat operations, so their losses are somewhat lower," the spokesperson said. (Bakhmut, by contrast, has been compared to a "meat-grinder" for its wave after wave of casualties.)
So far, Russian forces have been unable to make significant breakthroughs against Ukrainian defenses in the region, according to Cherevatyi.
