There's been doom and gloom on Russian media after Ukrainian forces seized previously Russian-held territory, with one top propagandist admitting he's "worried".
In a breakthrough that may be a turning point in Russia's invasion of Ukraine, Ukrainian forces moved in a "very sharp and rapid" advance, southeast of the Kharkiv region.
Ukrainian President Volodymyr Zelenskiy later said Kyiv's forces had liberated more than 30 settlements in the Kharkiv region so far and that fighting continued in the eastern Donbas region and the south.
And while it was radio silence for a day, Russia effectively acknowledged that a section of its frontline had crumbled southeast of Ukraine's second-largest city Kharkiv.
"The enemy is being delayed as much as possible, but several settlements have already come under the control of Ukrainian armed formations," Vitaly Ganchev, head of the Russian-backed administration in the Kharkiv region, said on state television.
Kremlin propagandist Vladimir Solovyov admitted on his radio show Full Contact that "I'm worried".
"Naturally, we want for our guys to crush [the other side] and only to advance, but life doesn't work that way," he said.
And appearing on Solovyov's nightly program The Evening With Vladimir Solovyov, military expert Mikhail Onufrienko was downcast.
"This is a difficult war, it's a big war, the world hasn't seen wars of this magnitude since WWII, at least after Vietnam," he said.
"Objectively speaking, this is the most successful advance of the junta since February 24... We clearly don't have enough troops to contain them."
Zelenskiy adviser Oleksiy Arestovych, in a video posted on YouTube, said the Russian defenders in Izium were almost isolated. Citing what he described as reports from the front line, Arestovych said hundreds of Russians had died so far and several hundred more had been taken prisoner. Reuters was not able to immediately verify his claim.
Supply lines
The Russian defence ministry released video of military vehicles speeding along a highway, saying they showed reinforcements rushing to defend the area.
Ukrainian officials released videos showing soldiers raising flags and posing in front of street signs in villages and towns across part of previously Russian-held territory.
One image showed troops a highway welcome sign for Kupiansk, previously more than 50 km inside Russia's front line. The city is an important target as the junction of several of the main railway lines supplying troops at the front.
Ukraine kept independent journalists out of the area.
Western military analysts said the advance could shut the supply lines Moscow has relied on to sustain its force in eastern Ukraine, and potentially leave thousands of Russian troops encircled.
Such rapid advances have largely been unheard of since Russia abandoned its assault on Kyiv in March, shifting the war mainly into a grind along entrenched front lines.
"We see success in Kherson now, we see some success in Kharkiv and so that is very, very encouraging," U.S. Defense Secretary Lloyd Austin told a news conference in Prague.
The Ukrainian general staff said early on Friday that retreating Russian forces were trying to evacuate wounded personnel and damaged military equipment near Kharkiv.
Tens of thousands of people have been killed, millions have been driven from their homes and Russian forces have destroyed entire cities. Russia denies intentionally targeting civilians.
In the latest reported strike on civilians, Ukrainian officials said Russia had fired across the border, hitting a hospital in the northeastern Sumy region on Friday morning. Reuters could not independently confirm the report.
The centre of Kharkiv, which has been regularly bombarded, was hit by Russian rocket fire, wounding 10 people, including three children, Governor Oleh Synehubov said.
Breakthrough
The Ukrainians broke through in the east a week after Kyiv announced the start of a long-awaited counter-offensive hundreds of kilometres away at the other end of the front line, in the southern province of Kherson.
Ukrainian officials said Russia moved thousands of troops south to respond to the Kherson advance, leaving other parts of the front line exposed.
Russia's RIA agency quoted Russian-appointed Kherson authorities as saying some Ukrainian troops were captured and some Polish tanks they were using were destroyed. Reuters could not verify those reports.
Ukraine has been using new Western-supplied artillery and rockets to hit Russian rear positions in the south, with the aim of trapping thousands of Russian troops on the west bank of the wide Dnipro River.
Zelenskiy is scheduled to speak to US arms makers for the first time later in September, when he is expected to make an appeal for more weapons.
Washington has already provided more than $14.5 billion in military assistance to Ukraine since the invasion.
Separately, the U.N. nuclear watchdog said on Friday shelling had destroyed power infrastructure in the southern Ukrainian city of Enerhodar where staff operating the Russian-held Zaporizhzhia nuclear power station live, posing a growing threat to the plant.
