Terrified Russian troops were sent running after a Ukrainian bomb landed at their feet in an aerial attack.

Footage of the assault on the Russian base was filmed by the 30th Mechanised Brigade named after Prince Konstanty Ostrogski, a formation of the Ukrainian Ground Forces.

It did not say where in Ukraine the attack was filmed.

The Ukrainian brigade said on 9th May: “As an enemy in training in Ukraine, we tested their physical fitness.

“The topic of the lesson for the ‘second army of the world’: basic physical exercise ‘shuttle run with full underpants’.”

The brigade added: “Occupiers, get ready: we have set a course for the second semester; train to squeeze into the ground in which you will remain.”

In the footage, two armoured vehicles are seen parking outside a building as at least two soldiers hop out and walk towards the base.

A bomb falls, apparently missing the vehicles but blasting one soldier on foot.

The scene cuts and a group of soldiers are seen running along the outside of the building while apparently carrying a dead or injured colleague.

Russia troops invaded Ukraine on 24th February in what the Kremlin is now calling a “special military operation” to “protect Donbass”. Today marks the 76th day of the campaign.

From 24th February to 10th May, the total combat losses of Russian troops stand at around 26,000 personnel, according to the General Staff of the Armed Forces of Ukraine.

The Ukrainian military also claims that Russia has lost 1,170 tanks, 2,808 armoured fighting vehicles, 519 artillery systems, 185 multiple launch rocket systems, 87 anti-aircraft systems, 199 warplanes, 158 helicopters, 1,980 motor vehicles, 10 fuel tankers, 12 vessels, 380 unmanned aerial vehicles, 41 units of special equipment and 94 cruise missiles.

This week, Vladimir Putin addressed a huge military parade on Red Square in Moscow to commemorate the defeat of Nazi Germany at the hands of the Soviet Union in World War II.

The Russian President used his speech to claim that Russian troops in eastern Ukraine were “defending the motherland”. He also said that the “special military operation” in Ukraine was necessary and was provoked by the West.
