VLADIMIR Putin has sent out a chilling warning to the West saying he will continue to unleash his devastating new hypersonic missiles.
The Russian despot has already threatened to strike the UK and US "if necessary" with the destructive "Oreshnik" hypersonic ballistic weapon.
Kyiv fears Russia may already have 10 of the terrifying weapons in its arsenal with Putin vowing to mass produce dozens more.
One of the "unstoppable" missiles has already been launched onto Ukraine on Thursday as it tore through the city of Dnipro.
Putin proudly claimed following the strike that his new catastrophic toy travels at 10 times the speed of sound and therefore couldn't be intercepted.
The assault on Ukraine was at first believed to be an intimidation tactic to show off Vlad's bad intentions if he is crossed by Nato.

In a chilling press conference, he announced that the aim of the attack was to test out the weapons.
President Zelensky told his war-embattled nation that Putin is using Ukraine as a "testing ground" for his new weapons.
Russia's tyrant has now vowed to continue conducting tests of the Oreshnik weapons in the coming weeks.
He said in a meeting with military chiefs: "We will continue these tests, including in combat conditions, depending on the situation and character of the security threats posted to Russia."

Putin also made it clear that he has ordered his men in Moscow to put the weapon into "serial production".
He said: "We need to begin serial production. The decision has in effect been taken."
Ukraine is still firmly backing itself to outmanoeuvre and overcome Russia's increased aggression.
Fearless officials believe Russia only has a few "Oreshnik" hypersonic ballistic missiles left in their arsenal.
A Ukrainian source close to the General Staff believes Russia only has a limited supply of the experimental missiles, reports RBC-Ukraine.
They added that with the help of Nato allies, they will soon be able to stop the Oreshnik in its tracks.
This confidence comes from the growing strength and unity between the UK and US.
Both nations finally allowed Ukraine to use British-made Storm Shadow and US-supplied ATACMS missiles to strike inside Russia this month - angering an already paranoid Putin.
The Kyiv-based source feels that this relationship will help them secure more weapons to counter the Oreshnik.
They added: "Ukraine will initiate negotiations on an attempt to counter such weapons together with partners.
"Either obtaining the appropriate systems capable of shooting them down, or carrying out the modernisation of the Patriot systems."
Nato and Ukraine are due to hold emergency talks on Tuesday to discuss the next steps in the over 1,000 day conflict.
Global reactions to Putin's missile threats
President Zelensky said in a televised address that the "Russian missile threat" can't be ignored by the West.
Britain’s defence secretary John Healey said Russia had been planning Thursday's strike “for months”.
And Lieutenant General Rob Magowan came out with an unsettling statement to the House of Commons defence committee.
He said Britain's armed forces would be ready to fight their Russian counterparts should mad Vlad invade another Eastern European nation.
Prime Minister Sir Keir Starmer also blasted Russia's "irresponsible rhetoric" as he said the UK has been drawn into the conflict by supplying weapons.
He labelled Russia the "aggressor" and said the war could end today if Putin stopped his dangerous strikes.
Nato's Eastern European members, including Latvia and Estonia, have been anxiously watching Russia's bloody invasion of Ukraine since it began in 2022.
Finland, which borders Russia to its east, has ramped up national security by publishing advice for citizens to prepare "for incidents and crises".
Nordic citizens were also told to prepare for war and handed chilling survival guides.
Polish Prime Minister Donald Tusk has even spoken about how the conflict is entering an "unknown phase" with deranged Putin hellbent on seizing Ukraine as his own.
Tusk said: "The war in the east is entering a decisive phase, we feel that the unknown is approaching.
"The conflict is taking on dramatic proportions. The last few dozen hours have shown that the threat is serious and real when it comes to global conflict."
How Ukraine could turn war around in WEEKS using US missiles
EXCLUSIVE by Sayan Bose, Foreign News Reporter, and Georgie English, Foreign News Reporter
After 1,000 days of Vlad's gruelling war in Ukraine, the conflict has left more than a million soldiers and civilians dead or wounded.
Putin's forces invaded their neighbouring nation in February 2022 as part of the deluded tyrant's plan to rebuild the Soviet Union amid his paranoid fears over Nato.
Almost three years later, Kyiv's battle-weary troops are fighting to the death on multiple fronts.
They have faced several setbacks in the grinding conflict as Russia has made slow but incremental gains over Ukrainian territory.
But the green light from the US that now allows Ukraine to use long-range ATACMS missiles could be a game changer, an expert has said.
Colonel Hamish de Bretton-Gordon told The Sun how Ukraine could turn the war around in six weeks when provided with unwavering support from key allies in the West.
The former British army officer said Washington's decision to allow Ukraine to use ATACMS is a "significant development".
He explained: "Since day one Putin and his close aides have been threatening a nuclear strike if we escalate it, and today is the 1,000th day of this conflict, and it hasn't happened.
"It should embolden our leaders, who must now realise that Putin's threats are completely hollow.
"With the Russian boxer on the ropes, now is the time that we enable the Ukrainians to absolutely put in the killer punch and be in a really good position for the expected ceasefire."
He added: "The fact that the Russians have been so vehement in their verbal attacks against the use of Nato missiles shows that this is a significant step.
"It could allow Ukraine to gain a good position in [the next] six weeks which will be important for Zelensky if Trump forces a ceasefire after getting back in office."
And Germany's World War Three preparation plans were also revealed in a 1,000-page secret document.
China has reiterated calls for "calm" and restraint by all parties in the war.
It comes as Russia's invasion of Ukraine dramatically intensified this week.
Kyiv launched US ATACMS missiles against Putin's territory overnight on Monday - and British Storm Shadow rockets on Wednesday.
Russia's ambassador to the UK, Andrei Kelin, claimed the use of Storm Shadow missiles against a military site in Russia meant Britain “is now directly involved in this war”.
Moscow has made similar claims in the past over Western support for Ukraine.
