Footage shows how Ukrainian soldiers are raining down destruction on the Russian invaders while promising to subject them to a living hell until they leave their country.

It is unclear where exactly in Ukraine the footage was filmed, but it was obtained from the 14th Separate Mechanized Brigade - also known as the 14th Separate Mechanized Brigade named after Prince Roman the Great - of the Ukrainian Ground Forces on the evening of Friday, 15th July.

The 14th Separate Mechanized Brigade said in a statement: 'There is no better sight than fire burning the enemy!

'They do not expect the biblical hell, they will burn alive in the hell that we will provide for them - day and night, almost every hour!

'The princely soldiers burn the abomination! Everything will be - Ukraine!'

The images and statement were also relayed by the Ground Forces of the Armed Forces of Ukraine.

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

The General Staff of the Armed Forces of Ukraine reported that between 24th February and 18th July, Russia had lost about 38,450 personnel, 1,687 tanks, 3,886 armoured combat vehicles, 849 artillery units, 248 multiple launch rocket systems, 113 air defence systems, 220 warplanes, 188 helicopters, 690 drones, 166 cruise missiles, 15 warships, 2,753 motor vehicles and fuel tankers, and 70 units of special equipment.

President Volodymyr Zelensky has dismissed Ukraine's head of the security service and its prosecutor general, saying that over 60 of their employees have been 'working against' the country in territories currently occupied by Russia.

Ukrainian military officials have said that Russia is preparing the next stage of its invasion after Moscow said that its forces in Ukraine will increase military activities in 'all operational areas.'

Ukraine has said that Russia appears to be preparing its units for an attack on the city of Sloviansk, in the eastern region of Donetsk.

The British Ministry of Defence (MoD) has said that Russia is also reinforcing its defensive military positions in areas that it currently occupies in southern Ukraine.

The British MoD has also said that Russia has used the private military company Wagner to reinforce frontline forces and to mitigate manning shortfalls and casualties. The MoD believes that Wagner has played a key role in recent fighting, including in the capture of Ukrainian cities, but they also said that this fighting has inflicted heavy casualties on the group, which has caused them to lower their recruitment standards.

The British MoD also said that the head of Wagner, Russian oligarch Yevgeny Prigozhin, has recently been made a Hero of the Russian Federation for Wagner's performance in Luhansk. The MoD said that this took place 'at a time when a number of very senior Russian military commanders are being replaced' and is therefore 'likely to exacerbate grievances between the military and Wagner. It is also likely to impact negatively on Russian military morale.'

European Commission President Ursula von der Leyen is travelling to Azerbaijan in a bid to secure a supply of natural gas for the European Union, as the block attempts to reduce its reliance on energy supplied by Russia.

The EU is also meeting to discuss increasing sanctions against Russia.
