Russia has reported heavy fighting along the front in southern Ukraine, where bloggers described the first sightings of German and US armour, signalling that Ukraine’s long-anticipated counterattack is under way.
With virtually no independent reporting from the front lines and officials in Kyiv saying little, it was impossible to assess whether Ukraine was penetrating Russian defences in its bid to drive out occupying forces.
“We can state for sure that this offensive has begun,” Russian President Vladimir Putin said in Sochi.
“Ukrainian troops did not achieve their goals in any sector.”
The counteroffensive is ultimately expected to involve thousands of Ukrainian troops trained and equipped by the United States and European allies.
Russia, which has had months to prepare its defensive lines, says it has repelled attacks since the start of the week.
Ukraine has said its main effort has yet to begin.
Russia and pro-war bloggers reported intense battles on Friday on the Zaporizhzhia front near the city of Orikhiv, around the mid-point of the “land bridge” linking Russia to the Crimea peninsula, seen as one of Ukraine’s likeliest targets.
Ben Barry, senior fellow for land warfare at the International Institute for Strategic Studies, said reports from the Russian bloggers of German-made Leopard tanks and US Bradley armoured vehicles near Tokmak south of Orikhiv, if confirmed, would provide the first evidence that Ukraine’s new brigades of foreign-armed troops had joined the battle.
In all, Ukraine has 12 brigades totalling 50,000-60,000 troops ready to unleash in the counteroffensive.
Nine of the brigades have been armed and trained by foreigners.
“They’ve got a choice of how many they commit initially and how many they keep in reserve in case the battlefield dynamics change,” Barry said, adding that Ukraine’s initial priority would be trying to keep the Russians off balance and gain tactical surprise through deception and camouflage.
The Russian defence ministry said: “The armed forces of Ukraine continued attempts to conduct offensive operations in the southern Donetsk and Zaporozhzhia directions.”
It said its troops had repelled two Ukrainian assaults south of Orikhiv and four near Velyka Novosilka further east, where it said Ukraine’s attack force included two battalions of troops supported by tanks.
Several battalions of up to 1000 troops comprise a brigade.
Ukraine has said almost nothing about the southern front, where it is widely expected to attempt its main push towards the coast.
Deputy Defence Minister Hanna Maliar said only that battles were continuing for Velyka Novosilka and Russian troops were mounting “active defence” at Orikhiv.
Ukraine has reported gains of territory around Bakhmut, which Russian forces captured last month.
Ukraine generally bars journalists from reaching its side of front lines during offensive operations.
The initial days of the counteroffensive have been overshadowed this week by a huge humanitarian disaster after the destruction of the Kakhovka dam holding back the waters of the Dnipro River that bisects Ukraine.
Thousands of people have been forced to flee homes flooded in the war zone, vast nature preserves have been wiped out and the destruction to irrigation systems is likely to cripple agriculture across much of southern Ukraine for decades.
Ukraine said at least four people had died and 13 were missing.
Ukraine’s security service released a recording on Friday of what it described as an intercepted phone call in which a Russian soldier confides to another man that a Russian sabotage group had blown the dam up.
Russia says Ukraine sabotaged it.
In his nightly video address, delivered on a train after a visit to the flood zone, President Volodymyr Zelenskiy thanked Ukrainian troops and repeated earlier claims of success in Bakhmut but gave no further account of fighting.
“We see every detail. But it’s not time to talk about it today,” he said.
