BRITAIN’S state-of-the-art Storm Shadow missiles could soon be used by Ukraine to blitz targets deep inside Russia, the German chancellor indicated.

According to Friedrich Merz, key supporters of Ukraine, including Germany, France, the UK, and the US, have removed the limitations on the locations where the weapons they supply can be utilized.

Chancellor Merz announced on Monday: “Weapons delivered to Ukraine now come without range restrictions – not from the British, not from the French, not from us, nor from the Americans.”

He continued, “This development allows Ukraine to defend itself more effectively, potentially by targeting military sites within Russia. Until now, such actions were rare, but Ukraine now has the capability to do so.”

In November last year, the US authorised Ukraine to use American long-range missiles called ATACMS against targets inside Russia.

In the same month, Britain gave the green light for Ukraine to fire our Storm Shadow missiles at Russia.

France has supplied its Scalp missiles to Ukraine, and reiterated in November that strikes on military targets inside Russia were an option.

It was unclear at the time whether there were range restrictions on the use of these weapons since then – but Merz’s comments imply there were.

He did not elaborate on when the decision was reached by each of the countries to allow unchecked deployment of the weapons – and there has been no official comment from the other name-checked nations.

The Kremlin fumed that the increased fire-power to Ukraine would be “dangerous” and counter-productive to peace.

Spokesman Dmitry Peskov said: “If these decisions have indeed been made, they are completely at odds with our aspirations for a political (peace) settlement.

“These are quite dangerous decisions, if they have been made.”

Britain’s bunker-busting Storm Shadow rockets are a nightmare for enemies as they are capable of dodging air defences.

The £800,000 missiles – already being fired within Ukraine – use GPS to precisely hit targets, and can travel at 600mph.

Geramany’s equivalent is the long-range Taurus missile system.

The previous chancellor, Olaf Scholz, was a staunch supporter of Ukraine but held back from supplying the weapons, concerned it might escalate tensions.

Merz has previously said he supports sending Taurus missiles to Ukraine, but did not confirm on Monday whether his government had begun to do so.

His government has declared it will no longer provide details about its weapons being used in Ukraine, opting instead of a position of strategic ambiguity.

Merz was less ambiguous about his thoughts on Putin.

He said it was clear that Putin was approaching the conflict “harder than before”, and the he “obviously sees offers of talks as a sign of weakness”.

Russia launched devastating volley of missiles into Ukraine, including Kyiv, over the weekend.

In the largest-scale aerial attack of the war, Russia sent 367 drones and missiles over the border, killing at least 12 and injuring dozens.

Apartment blocks were set ablaze by the barrage as residents in the Ukrainian capital fled to underground shelters amid the sound of anti-aircraft fire.

Explosions rocked the city during a seven hour raid as fireballs lit up the skyline long into the early hours.

In response, President Volodymyr Zelensky said: “Unfortunately, the Russians show no signals of a ceasefire. They are not yet ready to end the war.”

“Therefore, all our forms of pressure, all our work with partners to put pressure on Russia, are absolutely necessary.

“Pressure convinces. Pressure on the battlefield. Pressure on the economy – and that is exactly what sanctions are for.”

In the wake of the bloodbath Trump said Putin had “gone absolutely crazy” and was “needlessly killing at lot of people”.

The Kremlin sought to cool tensions with the White House by thanking Trump with his help in peace negotiations but claiming that this “crucial moment” would inevitably lead to “emotional overload”.

Russia is also reportedly amassing a 50,000-strong force on the border with the Ukrainian city Kharkiv.

The Ukrainian military first reported in April that the Kremlin was gathering troops for a fresh assault on Ukraine’s second-largest city.

Military analysts believe Putin is trying to press home his advantage and capture more Ukrainian land.

They warn that he only has a “four-month window” to achieve a breakthrough in Ukraine this year.

And this could be the beginning of Russia’s summer offensive targeting the border city of Kharkiv – the “fortress” city of Ukraine which put up the maximum resistance at the start of the invasion.

However, a security expert told The Sun he believes that Putin has four glaring vulnerabilities that could ultimately lead to his downfall.

Security expert David H. Carstens also told how the tyrant’s “Achilles’ heel” is putting Russia on track to have the highest number of casualties this year since the war started.
