A NEW front in Vladimir Putin’s bloody war erupted as Ukraine and Russia traded deadly Black Sea strikes after peace talks collapsed.

The tit-for-tat attacks were the fiercest in months and marked a chilling escalation in a war showing no signs of ending.

In the Russian resort city of Sochi – Putin’s glittering showcase to the world and personal playground – massive Ukrainian drones tore through vital infrastructure.

Explosions rocked oil depots, ignited railway warehouses, and tore apart road links in Sirius Federal Territory, where elite schools, luxury developments, and whispers of Putin’s own children echo.

In an embarrassing blow to the Kremlin, a Russian S-400 missile system misfired during the chaos, smashing into a residential block and killing at least two civilians.

One woman was among the dead, and another 11 people were wounded.

Tourists at Sochi’s five-star beachside hotels were seen cowering in underground car parks as their luxury summer breaks were shattered by war.

This was the first major Ukrainian strike on Sochi in almost two years – and the symbolism couldn’t be clearer.

The city is home to Russia’s most elite gymnastics academy run by Alina Kabaeva, Putin’s long-time secret lover.

It’s also just a stone’s throw from the palace Mad Vlad is building after razing his last one – and only a mile from the Sirius school where he once held private talks with Donald Trump.

Ukraine used Lyutyi‑196 long-range drones in the daring raid that lit up the night sky with fireballs.

The Lukoil-Yugnefteprodukt oil depot exploded in flames as local officials scrambled to control the chaos.

Sochi airport was also shut down, delaying more than 100 flights.

While Sochi burned, the heart of Odesa bled.

The historic Ukrainian port city, often described as the soul of the nation, suffered yet another hellish night under a hail of Russian drones.

A nine-storey residential building was torn apart from the fifth to eighth floors, and the city’s beloved Privoz Market – a cultural landmark since 1827 – was engulfed in flames.

Regional governor Oleh Kiper said: “There is damage to architectural monuments in the historic centre of Odesa, which is under UNESCO protection.”

Russia also launched drone strikes on Mykolaiv and a missile assault on Cherkasy, injuring seven people and a child.

Fires raged across Ukrainian industrial sites as sirens screamed through the night.

All this, just hours after peace talks in Istanbul collapsed into bitter recriminations.

Kremlin negotiator Vladimir Medinsky admitted the two sides were “quite far from each other”.

Ukraine’s Rustem Umerov demanded an immediate ceasefire and face-to-face negotiations.

He warned: “We emphasise that the ceasefire must be real.

“It must include a complete halt to strikes on civilian and critically important infrastructure.”

‘Prepping for nuclear war’

As the bloodshed on the ground escalates, Putin’s propaganda machine turns even more apocalyptic.

Leading Russian media outlets – or Kremlin mouthpieces – have begun preparing their citizens for nuclear war.

Newspapers such as Komsomolskaya Pravda ran chilling features warning that war with the West could come before the end of the decade, fuelled by what they claim is Nato aggression.

Accusing the West of wanting to “dismember” Russia to access its resources, Russian military analyst Andrei Klintsevich warned: “The aim is to provoke Russia… and launch direct confrontation.”

He called for a nuclear test in the Arctic – the first since the Cold War – in a move meant to terrify Western powers.

The warnings coincided with threats from Putin’s infamous crony Dmitry Medvedev, who claimed World War Three has already begun, and urged Russia to bomb the West.

Medvedev, deputy chairman of Russia’s Security Council, raged that Nato and the West are effectively already at war with Russia as he pushed the Kremlin’s view that his country is the victim.

That’s despite it being Russia who invaded Ukraine and is continuing to wage a bloody war.

The Kremlin’s fury was further stoked after US General Christopher Donahue declared Nato could capture Kalinigrad – the strategic fortress Russia clings to in the heart of Europe – “faster than we’ve ever done before.”

It comes after Trump threw his own firepower to the mix.

He pledged to arm Ukraine with advanced defence systems and slap Russia with brutal 100 per cent tariffs – unless Putin strikes a peace deal within 50 days.

Meanwhile, Volodymyr Zelensky has found himself facing a new kind of battle – not with Putin, but with his own people.

The Ukrainian leader is under intense fire after signing a controversial anti-corruption bill that critics say hands him near-absolute power over previously independent watchdogs.

Thousands poured into the streets of Kyiv in the biggest anti-government protest since the war began.

“We chose Europe, not autocracy,” read one handmade placard.

Another one read: “My father did not die for this.”

Zelensky insisted the law was needed to purge Ukraine’s anti-corruption agencies of Russian infiltration, claiming: “We all share a common enemy: the Russian occupiers…

“Those who work against Ukraine must not feel comfortable or immune to the inevitability of punishment.”

But his assurances did little to calm protesters, which included Kyiv’s mayor and former heavyweight champion Vitali Klitschko, who said bluntly: “Sapo and Nabu must remain independent institutions.”

The protests have now spread to Lviv, Dnipro and even battle-hardened Odesa, adding political turmoil to an already exhausted nation.
