Ukrainian forces are claiming to have launched successful stealth night attacks on Russian ammo depots.

The attacks reportedly took place in the village of Chornobaivka, in the southern Ukrainian region of Kherson Oblast.

The non-governmental organisation StratCom Ukraine said this morning: “Chornobaivka – Russia (15 – 0).”

The video, however, is so dark that it is impossible to see what the target is or if it has been hit.

StratCom added: “Ammunition depots of the 22nd Army Corps of the Coast Guard of the Black Sea Fleet of the Russian Federation were destroyed.

“Believe in the Armed Forces of Ukraine! Glory to Ukraine!”

Russian troops invaded Ukraine on 24th February in what the Kremlin is calling a “special military operation”.

Today marks the 50th day of the invasion. From 24th February to 14th April, the total combat losses of Russian troops stand at about 19,900 personnel, according to the General Staff of the Armed Forces of Ukraine.

The Ukrainian military also claims that Russia has lost 753 tanks, 1,968 combat armoured vehicles, 366 artillery systems, 122 MLR systems, 64 anti-aircraft systems, 160 warplanes, 144 helicopters, 1,437 vehicles, seven vessels, 76 fuel tankers, 134 operational-tactical level UAVs, 25 units of special equipment, and four mobile SRBM systems.

In recent developments, the Russian Ministry of Defence (MoD) said the Moskva, which is the flagship vessel of its Black Sea fleet, had been seriously damaged.

The Russian MoD explained that a fire caused ammunition onboard to explode, but it added that the cruiser remained afloat.

Officials said the crew had been evacuated and that the vessel would be towed to port.

Ukrainian officials claimed their troops struck the cruiser with two missiles and that it started sinking.

Meanwhile, the United States has said it is sending Ukraine more artillery, armoured vehicles and helicopters.

And the Kremlin says Russian troops have gained full control of the south-eastern Ukrainian port city of Mariupol.

The Ukrainian MoD, however, says its troops are still holding out there.

Elsewhere in the country, Wladimir Klitschko – who is the brother of the Mayor of Kyiv, Vitali Klitschko – told reporters that the Ukrainian capital is slowly coming back to life.

His comments came following the withdrawal of Russian troops from north of the capital after the Kremlin decided to focus its military efforts in eastern and southern Ukraine.
