Russia claimed that it has destroyed Ukrainian armoured vehicles and mortars, as well as command posts, using tanks and howitzers.

The footage begins by showing a self-propelled gun firing rounds, presumably at unseen Ukrainian positions, before tanks bearing the now infamous 'Z' symbol can be seen manoeuvring into position.

The 'Z' mark - as well as the letters 'V' and 'O' - is a symbol that can be seen painted on Russian military vehicles taking part in the invasion of Ukraine.

The images then show at least two Russian tanks opening fire before the footage ends.

The video was obtained from the Russian Ministry of Defence (MoD) on Sunday, September 18, along with a statement claiming that the images show how Russian 'airborne troops destroyed enemy armoured vehicles, artillery and mortar batteries, command posts of the Armed Forces of Ukraine.'

The Russian MoD also claimed: 'The military personnel of the Airborne Forces destroyed armoured vehicles, artillery and mortar batteries, command posts of the Armed Forces of Ukraine during the special military operation, showing determination and courage.

'Russian paratroopers with heavy fire from 2S1 'Gvozdika' 122-mm self-propelled guns and tanks liquidated long-term firing points. After successful combat work, the 'winged infantry' quickly changed their firing positions.'

The claims or the footage have not been independently verified. The 2S1 'Gvozdika' 122-mm self-propelled gun is a type of Soviet-era howitzer.

Russia invaded Ukraine on February 24 in what the Kremlin is still calling a 'special military operation.'

The General Staff of the Armed Forces of Ukraine reported that between 24th February and 19th September, Russia had lost about 54,650 personnel, 2,212 tanks, 4,720 armoured combat vehicles, 1,313 artillery units, 312 multiple launch rocket systems, 168 air defence systems, 251 warplanes, 217 helicopters, 920 drones, 238 cruise missiles, 15 warships, 3,581 motor vehicles and fuel tankers, and 125 units of special equipment.

Russia has claimed that its casualties have been much lower but provides infrequent updates on its latest figures.

The Ukrainian military has said that it has repelled Russian attacks in the east of the country, in the Kharkiv region, and in the south of the country, in the Kherson region, adding that its troops have made further advances in Kharkiv, taking the eastern bank of the Oskil River.

Ukraine's President Volodymyr Zelensky has said that there will be no lull in fighting to retake Ukrainian land occupied by Russian forces. He said in his nightly address on Sunday, September 18: 'Perhaps it seems to some of you that after a series of victories we now have a lull of sorts,' adding: 'But there will be no lull. There is preparation for the next series… For Ukraine must be free. All of it.'

The General Staff of the Ukrainian Armed Forces said on Sunday that it had carried out 20 airstrikes against Russian positions in the last 24 hours.

British intelligence has said that Russian strikes on civilian infrastructure have increased. It said on Sunday: 'As it faces setbacks on the front lines, Russia has likely extended the locations it is prepared to strike in an attempt to directly undermine the morale of the Ukrainian people and government.'

The Canadian Prime Minister, Justin Trudeau, told reporters in London on Sunday, where he is attending the funeral of Queen Elizabeth II, that the mass graves that have been found in Izium are evidence of Russian war crimes against Ukraine. He said: 'Obviously the UK and Canada have been two of the strongest countries in standing up in support of Ukraine and pushing back against Russia's illegal actions.'

Prime Minister Trudeau said that these actions 'increasingly, clearly include war crimes, include absolutely unacceptable crimes, whether we think of what we found in Bucha or the discovery of mass graves in the reclaimed territories by Ukraine.'
