KYIV - Ukraine hailed a lightning counteroffensive it said recaptured swathes of its territory in the east and south, as US Secretary of State Antony Blinken visited the capital, Kyiv, to pledge more aid.
Ukrainian President Volodymyr Zelensky said in a video address Thursday that Ukrainian forces had "liberated dozens of settlements" and reclaimed 1,000 sq km of territory in the east and south since Sept 1.
Mr Zelensky also posted a video in which Ukrainian soldiers said they captured the eastern town of Balakliia near Kharkiv, the second largest city in Ukraine.
On Friday, a Russian-installed official in the Russian-controlled part of Ukraine’s Kharkiv region said Ukrainian forces had registered a “substantial victory” by breaking through Russian defences in the region.
Speaking to Russian state television on Friday, Vitaly Ganchev said: “The very fact of a breach of our defences is already a substantial victory for the Ukrainian armed forces.” Russia’s defence ministry posted video footage of what it said were Russian troops being sent to the Kharkiv region.
Video posted to a Ukrainian news aggregator appeared to show the Russians had left behind trucks, artillery and ammunition.
But Ganchev said Russian forces fought off a Ukrainian attempt to encircle and capture Balakliia, which he said remained in Russian hands.
Earlier, Ukrainian Brigadier-General Oleksiy Gromov said troops advanced up to 50km behind Russian lines and recaptured more than 20 villages in the Kharkiv region.
The Ukrainian military said early Friday Russian forces were trying to evacuate wounded personnel and damaged military equipment in the areas of Vilkhuvatka village, south-west of Kharkiv, and Borodoyarske, to the south-east.
'As long as it takes'
Mr Blinken said Ukrainian forces were making progress, as he pledged US support for "as long as it takes".
"We did get a comprehensive update on the counteroffensive and, again, it's very early, but we're seeing clear and real progress on the ground, particularly around Kherson, but also some interesting developments in the Donbas in the east," Mr Blinken told reporters before leaving Kyiv.
If the gains are confirmed and held, they would be a serious blow for Russia, which Western intelligence services say has suffered huge casualties.
The gains would also represent a big boost for Ukraine, which is keen to show its Western backers that it can turn the tide in the conflict and deserves more of their support.
This week's surprise counteroffensive in the Kharkiv region saw Ukrainian forces make a sudden and deep thrust behind Russian lines.
Ukraine has for weeks been talking about a big counteroffensive in the south around Kherson. Western military analysts believe Russia may have left itself exposed in other areas as it rushed to reinforce the south.
Ukrainian presidential adviser Oleksiy Arestovych underscored that possibility.
"In principle, this is a huge success. We found a weak spot where the enemy wasn't ready," he said in a video posted on YouTube.
Mr Arestovych said Ukraine's campaign in Kherson was advancing more slowly than in the Kharkiv region, but that the eastern drive was "methodical and organised". He said Kyiv's forces were well placed to regain more Kharkiv towns.
Russia's state news agency RIA quoted Russian-appointed Kherson authorities as saying some Ukrainian troops were captured during the counterattack and an undisclosed number of Polish tanks they were using had been destroyed.
Mr Blinken announced US$2.2 billion (S$3.1 billion) in new military financing to Ukraine and 18 other countries deemed to be at risk of Russian aggression. Approximately US$1 billion will go to Ukraine. '
The United States also announced a separate US$675 million in weapons to the country.
'We are scared'
The Kharkiv region borders Russia and its main city, Kharkiv, has for months been struck by Russian missiles after its forces failed to capture it in the early stages of its Feb 24 invasion.
Missiles hit multiple areas of Kharkiv again Thursday, causing widespread damage and casualties, according to the Kharkiv region prosecutor's office.
Officials reported more Russian shelling in Kharkiv overnight, and Governor Oleh Synehubov said one person was killed.
"We are scared… You can't get used to it, never,"resident Olena Rudenko told Reuters. Russia has repeatedly denied targeting civilian areas.
Ukraine is under pressure to demonstrate progress on the ground before winter sets in, amid threats by Russian President Vladimir Putin to halt all energy shipments to Europe if Brussels goes ahead with a proposal to cap the price of Russian gas.
Russia has confirmed fighting in the Kharkiv region but has not confirmed any territorial losses, though unverified social media accounts run by Russian military experts have suggested Russia did suffer setbacks and would need to reinforce.
Heavy fighting was also reported Thursday in areas near the Russian-held Zaporizhzhia nuclear power station in southern Ukraine, after Kyiv warned it might have to shut down the plant to avoid disaster.
Mr Putin said Wednesday that Russia would not lose what he calls its "special military operation" in Ukraine, an exercise he has described as an attempt to preemptively protect his country's security against an expanding Nato, the Western military alliance. REUTERS
