KYIV, June 9 (Reuters) - Moscow and Kyiv both reported heavy fighting in Ukraine on Friday, with bloggers describing the first sightings of German and U.S. armour, signalling that Ukraine's long-anticipated counterattack was under way.

With virtually no independent reporting from the front lines and 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."

Ukraine's President Voldymyr Zelenskiy said he had discussed tactics and "achievements" with military leaders but gave little away.

"For our soldiers, for all those who at this time are engaged in particularly heavy combat. We see your heroism, and we are grateful for every moment of your lives," he said in his nightly video address. "Ukraine is as free as you are strong."

Ukrainian military analyst Oleksander Musiyenko, interviewed on Ukrainian NV Radio, said Ukraine was making gains but dismissed Russian reports of a major counter-offensive in south-central Zaporizhzhia region.

"This is simply not true. It is not the main phase of the counter-offensive. It is merely a phase and not the large drive from which we can expect a rapid breakthrough and hundreds of kilometres of liberated territory," Musiyenko said.

The counteroffensive is ultimately expected to involve thousands of Ukrainian troops trained and equipped by the West. The United States announced an extra $2.1 billion in security assistance on Friday, including air defence and ammunition.

Russia, which has had months to prepare its defensive lines, says it has repelled attacks since the start of the week. Kyiv has said its main effort has yet to begin.

Moscow and pro-war Russian bloggers reported intense battles 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 U.S. Bradley armoured vehicles near Tokmak south of Orikhiv, if confirmed, would provide the first evidence that Ukraine's new brigades of Western-armed troops had joined the battle.
