A pro-Putin propaganda TV channel has simulated a nuclear strike on London, that it claims would cause 850,00 deaths with a further two million casualties.

The latest bout of nuclear sabre rattling by the Kremlin comes as the UK ponders a decision to allow Ukraine‘s military to use Storm Shadow missiles to strike targets deep inside Russia.

The four minute video was broadcast on Tsargrad’s Telegram channel, which is owned by the Russia oligarch Konstantin Malofeev, 50 – a close Putin ally.

The investment banker and media mogul is also known as the “Orthodox Oligarch” because of his links to the Russian church. Originally published three months ago, the video has been recycled in an attempt to pile the psychological pressure on the UK.

The narrator begins by saying the simulation will replicate the effects of a 750 kiloton nuclear bomb exploding over the UK’s capital.

“Upon detonation, a fireball as hot as the sun rapidly expands, reaching a radius of 950 metres [1,039 yards],” the narrator explains.

“Anything trapped inside this fireball is instantly vaporised. In our simulation, the epicentre of the explosion is at Westminster. People within that radius won’t even feel anything because the nerve impulse transmission speed is slower.

“Within 5 km [3 miles] of the epicentre the blast radius city of London, Camden town, Kensington, Brixton these areas will receive the most destruction.”

The narrator claims the initial death toll could exceed 250,000 people, with a further 600,000 injured.

“According to various estimates, a further 450,000 people will die from burns, debris, injuries or radiation sickness, and over a million will be traumatised,” the narrator continues.

“Many of these injuries could prove fatal over the next days and weeks.Radiation sickness in particular will take lives days and weeks later. In time, about 100,000 more will be added to the death toll.”

A recent terrifying simulation of a nuclear attack by Nato on Russia has shown that tens of millions of people would be wiped out in the motherland.

The simulation, which was shared on X by @historyinmemes, estimates that 45.3 million Russians would be killed. It also showed that the entirety of the Russian mainland would be within range of Western nukes.

A 2019 simulation carried out by Princeton’s Science and Global Security programme and called “Plan A” also showed how a limited tactical nuclear exchange in Europe could escalate into a full-scale global atomic conflict.

It estimated that 91.5 million people would die within hours and many more in the months and years afterwards.
