Russia's air and missile forces have carried out air strikes against the cities of Lutsk and Ivano-Frankivsk in western Ukraine over the past 24 hours.
However, the momentum of Russian forces on the ground is still limited due to logistics problems and Ukrainian resistance.
The UK's defense ministry commented: "The determined resistance of the Ukrainian air defense forces is forcing Russia to rely on anti-aircraft weapons to launch attacks against targets deeper inside Ukraine."
According to the British Ministry of Defense, Russian planes supporting ground forces are relying on "inaccurate" weapons and their use significantly increases the likelihood of civilian casualties.
Ukraine's General Staff also said that Russian forces were regrouping after "suffering heavy losses". Ukrainian soldiers pushed a number of enemy units into "adverse positions" near the Belarusian border, behind the main Russian army.
Explosions continued to be heard near the capital, Kiev, but it was not clear whether the attack came from Russia or Ukraine.
According to CNN, fighting is still ongoing on the outskirts of the Ukrainian capital, with the northern regions in the most dangerous situation, including the suburbs of Bucha, Irpin and Hostomel, as well as the Vyshorod region to the east. North Kiev.
Fighting also escalated in the city of Brovary in northern Ukraine. Kiev mayor Vitali Klitschko told CNN that the city currently has only resources, including food and medical supplies, for one to two weeks.
Meanwhile, according to Interfax Ukraine, Ukraine accused the Russian military of arresting the mayor of Melitopol city Ivan Fedorov. This city is under Russian control.
