Russian forces are suffering an average of 400 casualties daily, according to a report from the U.K.'s Ministry of Defence.

The report said that Russia is struggling with "a crisis of combat medical provision."

"It is likely that many dedicated military hospitals are being reserved for officer casualties," the report said.

The Ministry of Defence added that half of Russian fatalities in the last 17 months could have been prevented with proper first aid.

Ukraine Deputy Minister of Defense Hanna Malyar released a statement Monday with updates on the ongoing counteroffensive.

Malyar said that Ukrainian forces liberated more than 14 square kilometers of territory from Russian forces last week, the majority of which came from the south.

The minister added that Russian forces are "on the defensive" in the direction of Bakhmut.

"The defense forces of Ukraine were able to capture the main heights near Bakhmut and have been holding the fortress city under fire control for several days," Malyar said.

Russian President Vladimir Putin met with Wagner Group leader Yevgeny Prigozhin days after the rogue paramilitary leader launched a failed uprising, the Kremlin said on Monday.

The June 29 meeting came about a week after the rebellion failed, Kremlin spokesman Dmitry Peskov said.

"Indeed, the president had such a meeting, he invited 35 people to it -- all the commanders of the detachments and the management of the company, including Prigozhin himself," Peskov said Monday, according to Interfax, a Russian newswire. "This meeting took place in the Kremlin on June 29, it lasted almost three hours."

Ukrainian troops have reportedly seized a small village on the Russian-occupied eastern bank of Dneipr after crossing the river from the liberated city of Kherson, according to Russian accounts on Tuesday.

A small Ukrainian force has managed to dig in to the village of Dachi after making a landing there a few days ago and are trying to expand the beachhead. Ukrainian troops in small boats crossed the river and landed at the base of the ruined Antonivskiy Bridge, which they destroyed last year.

Russian military bloggers reported very heavy fighting on Tuesday, saying Russian airborne units have been trying unsuccessfully to dislodge the Ukrainians for the past four days. Russian aviation and heavy artillery have been firing on the Ukrainian position.

So far, the Russian side claims some 70 Ukrainian soldiers are dug in, covered by intense artillery fire from across the river. The Russian accounts say Ukraine is trying to move reinforcements across. Video released by Ukraine also shows a Russian APC being destroyed in the village of Oleshkjy, further south, indicating the bank south of Kherson is now contested.

Ukrainian troops have also managed to advance and liberate Rivnopil, a village on the Zaporozhzhia front, breaking through after more than two weeks of fighting. It's notable because the Russians had been fighting hard to hold it.

Taken together the advance there, the landing in Kherson and advances near Bakhmut are small signs the Ukrainian counteroffensive may be starting to pick up steam and the Russians are coming under growing pressure.
