Russian defence chiefs have released a video of a high-precision supersonic Onyx cruise missile being deployed over a murky coast.

Kremlin officials claimed the missile was aimed at Ukrainian “military infrastructure”, but gave no details of what the target was or if the missile hit home.

The Russian Ministry of Defence (MoD) said: “DemilitariZation. The crew of the ‘Bastion’ coastal missile system on the Black Sea coast launched a high-precision ‘Onyx’ missile at military infrastructure of the Armed Forces of Ukraine.”

The footage shows the missile slowly rising into the air before levelling off and shooting across the horizon with a supersonic roar.

In a statement obtained by Newsflash on 8th April, the Russian MoD said: “The Russian Armed Forces carried out a missile strike with precision-guided weapons on Ukraine’s military infrastructure.

“As part of the fulfilment of the tasks of the special military operation, the Armed Forces of the Russian Federation launched another missile attack with precision weapons on the military infrastructure of the Armed Forces of Ukraine.

“The crew of the Bastion coastal missile system on the Black Sea coast launched the Onyx high-precision missile at a designated ground target in the territory of Ukraine.”

The Russian MoD styled the word “demilitarization” with a capital ‘Z’, which has been used in Russian propaganda as a sign of support for the invasion of Ukraine.

The attack came as the invasion, which the Kremlin is dubbing a “special military operation”, enters its 44th day.

From 24th February to 8th April, the total combat losses of Russian troops stand at an estimated 19,000 personnel, according to the General Staff of the Armed Forces of Ukraine.

The Ukrainian military also estimates that Russia has lost 700 tanks, 1,891 armoured combat vehicles, 333 artillery systems, 108 MLR systems, 55 anti-aircraft systems, 150 aircraft, 135 helicopters, 1,361 vehicles, seven vessels, 76 fuel tankers, 112 operational-tactical level UAVs, 25 units of special equipment and four mobile SRBM systems.

In latest reports, Ukraine says over 30 people have been killed and 100 injured after rockets hit a train station in the city of Kramatorsk, in eastern Ukraine’s Donbas region.

Donbas is where Russia is believed to be stepping up its offensive as it withdraws from the north of Ukraine.

Parts of Donbas have been under pro-Russian separatist occupation since 2014 as the so-called Donetsk and Luhansk People’s Republics, which were recognised as independent states by Russia just days before the invasion was launched.
