Vladimir Putin was facing the prospect of further setbacks in Ukraine as he appeared to be preparing Russians for a possible scaling back of his ambitions away from seizing Kyiv to fighting for control of the east.
Ukrainian president Volodymyr Zelensky hailed his troops as having delivered “powerful blows” to the invading forces as he urged Moscow to negotiate an end to the month-long war.
An adviser to the Ukrainian ministry of defense, Markian Lubkivskyi, predicted troops could on Saturday take back Kherson, the first major city that the Kremlin’s forces seized.
He was skeptical that the Russian President’s aims had truly changed away from trying to take the whole nation, but said it does appear “the enemy is focused on the eastern part of Ukraine”.
Moscow gave its first indication it could scale back its offensive when it said the “special military operation” would now focus on the “main goal, liberation of Donbas”, which borders Russia in the east of Ukraine.
Mr Zelensky’s forces were already believed to be regaining ground around the capital of Kyiv and the UK Ministry of Defense (MoD) said Russians are “proving reluctant to engage in large scale urban infantry operations”.
Instead, the MoD said, they were preferring the “indiscriminate use of air and artillery bombardments in an attempt to demoralize defending forces”.
However, there were fresh signs it was Mr Putin’s troops who were struggling with morale, as Western intelligence suggested a Russian brigade commander, Colonel Medvechek, was deliberately run down and possibly killed by his own troops.
Mr Lubkivskyi told BBC Radio 4’s Today programme: “We cannot believe the statements from Moscow because there’s still a lot of untruth and lies from that side.
“That’s why we understand the goal of Putin still is the whole of Ukraine.
“We can see now that the enemy is focused on the eastern part of Ukraine but we are ready for any kind of attacks in different Ukrainian places.”
The port city Kherson, in the south east, fell to the Russians early this month in their first major gain.
But Mr Lubkivskyi said: “I believe that today the city will be fully under the control of the Ukrainian armed forces.
“We have finished in the last two days the operation in the Kyiv region so other armed forces are now focused on the southern part trying to get free Kherson and some other Ukrainian cities.”
Mr Zelensky claimed in his night-time address that more than 16,000 Russian troops had been killed in the conflict as he called for Moscow to negotiate, but warned he would not give up sovereign territory.
In the UK, Policing minister Kit Malthouse was skeptical about Moscow’s statements hinting at a scaling back of its operations.
“I’m not qualified to say, but what I do know is there’s an awful lot of misinformation and disinformation flying around in this awful conflict,” he said.
“And we need to take care that what first appears may not in fact be the truth.
“Let’s hope there may well be a cessation of hostilities as soon as possible.”
Transport Secretary Grant Shapps signed new powers to seize two private jets worth tens of millions of pounds, one at Farnborough, the other at Biggin Hill, belonging to sanctioned Russian billionaire Eugene Shvidler.
“Putin’s friends who made millions out of his regime will not enjoy luxuries whilst innocent people die,” Mr Shapps said.
Facing unexpectedly fierce resistance, the Russian defense ministry said that having accomplished the “first phase” of military operations, its forces would concentrate on the Donbas region part-held by Moscow-backed separatist rebels.
Western officials said the Russian statement was a recognition its forces were overstretched and may have to “pause” operations around Kyiv and other cities while they focus on the east of the country.
“It is clear that Russia is recognizing that it can’t pursue its operations on multiple axes simultaneously,” one official said.
“Therefore it is having to concentrate its force, particularly its logistics supply and its firepower, on a more limited number of approaches.”
In the besieged city of Mariupol, authorities said about 300 people died in a Russian air strike earlier this month on a theater where hundreds of people were sheltering.
If confirmed, it is likely to lead to renewed calls for Western powers to step up military support for the Ukrainian forces.
Nato estimates that in four weeks of fighting, between 7,000 and 15,000 Russia troops have been killed in combat, compared to the 15,000 they lost in 10 years in Afghanistan.
