Ukrainian soldiers launch rockets from inside a building on the Sieverodonetsk front line.

Ukrainian soldier fires a rocket from inside a building, filling the entire room with smoke as the battle for the eastern Ukrainian city of Sieverodonetsk rages on.

The soldier, who has not been named, can be seen retreating from the window briefly to reload his rocket launcher before heading back to the window and firing again.

The footage also shows Ukrainian soldiers using assault rifles as they fire out the windows of the severely damaged building while also taking fire.

The video then cuts to a soldier also sporting a rocket launcher and firing from what appears to be a different, but also damaged, building at unseen enemies below before quickly retreating as the footage ends.

The images were obtained from the National Guard of Ukraine on Tuesday, 21st June, along with a statement saying: "Soldiers of the National Guard of Ukraine destroy the enemy in Sieverodonetsk."

They added: "Without rest, sleep or even a few minutes of silence, the Guards together with their comrades from other Defence Forces hold the city. The battles for Sieverodonetsk continue. The enemy receives from our military what he deserves - death."

The Land Forces of the Armed Forces of Ukraine also confirmed that the footage shows fighting "in the city of Sieverodonetsk", in the Luhansk Oblast region of eastern Ukraine.

Russia invaded Ukraine on 24th February in what the Kremlin is calling a "special military operation". Today marks the 119th day of the invasion.

The General Staff of the Armed Forces of Ukraine reported that between 24th February and 21st June, Russia had lost about 34,100 personnel, 1,496 tanks, 3,606 armoured combat vehicles, 752 artillery units, 239 multiple launch rocket systems, 98 air defence systems, 216 warplanes, 181 helicopters, 611 drones, 137 cruise missiles, 14 warships, 2,537 motor vehicles and fuel tankers, and 59 units of special equipment.

Russia has conducted an anti-ship missile exercise in the Baltic Sea amid escalating tensions with NATO member Lithuania after the country blocked the transit of goods to the Russian exclave of Kaliningrad.

Ukrainian forces have said that they have been successfully thwarting fresh Russian attempts to advance in the Kharkiv region of north-eastern Ukraine.

And Iryna Vereshchuk, Ukraine’s Deputy Prime Minister and Minister for Reintegration of the Temporarily Occupied Territories, has urged locals in the Kherson region to evacuate the area so as to help Ukrainian forces "deoccupy" the area.

Ukrainian President Volodymyr Zelenskyy visited Ukraine's southern frontline as Ukrainian forces mount a counter attack in the region to push back Russian troops.

The new head of the British Army, Gen Sir Patrick Sanders, has told British forces that they need to be ready to face Russia on the battlefield and said the British Army now needs to be capable of defeating Russia.

United States President Joe Biden has promised Kyiv another USD 1 billion in security assistance and weapons. And US General Mark Milley says Russia has lost around 20 to 30 per cent of its armoured force during the ongoing invasion.

President Zelenskyy said that a "historic week" has begun as Kyiv awaits a decision from Brussels regarding its EU candidate status.
